Veiled Threat and Diplomatic Protocol: A Critical Review of Recent Remarks
Subtitle: Philippine Sovereignty, Strategic Communication, and the Limits of Diplomatic Conduct
Central Argument: The October 15, 2026, remarks of Chinese Ambassador Jing Quan raise important questions about diplomatic restraint, strategic messaging, and the Philippines’ response to the continuing maritime dispute with China. Although the ambassador expressly stated that China would not choose force, his assertion that China could easily win if it resorted to force could reasonably be interpreted as coercive rhetoric. The incident invites a broader examination of psychological warfare, competing maritime claims, international law, and the diplomatic measures available to the Philippines.
This article examines the controversy through four lenses: overlapping maritime claims, psychological-warfare techniques, diplomatic accountability, and nonmilitary mechanisms for protecting Philippine national interests.
On October 15, 2026, Chinese Ambassador to the Philippines Jing Quan spoke to reporters on the sidelines of the Second Diliman Dialogue in Quezon City. He was responding to remarks by Philippine Defense Secretary Gilberto Teodoro Jr., who had described China as a regional troublemaker.
The Associated Press reported the following statement:
“If we want to use force, we may easily win. But no, we will not choose force and we love peace.”

Why does the distinction matter? The ambassador’s words contain both a declaration of peaceful intent and a statement about China’s potential military advantage. A critical analysis must consider both elements. It is reasonable to question whether the language was diplomatically appropriate without claiming, absent further evidence, that it proves an intention to launch military action.
II. INTRODUCTION
Introduction: Maritime Disputes, Strategic Messaging, and the Cost of Diplomatic Miscalculation
The South China Sea dispute is not simply a disagreement over geography. It concerns sovereignty, maritime jurisdiction, natural resources, freedom of navigation, national security, and the credibility of international law. For the Philippines, the dispute directly affects its maritime rights, the security of Filipino personnel, the livelihood of fishing communities, and its capacity to exercise lawful authority within its maritime zones.
China and the Philippines have competing positions regarding maritime features and maritime entitlements in parts of the South China Sea. China advances extensive historical and maritime claims, while the Philippines asserts rights grounded in the United Nations Convention on the Law of the Sea (UNCLOS) and the 2016 South China Sea arbitral award. These positions must be examined carefully because territorial sovereignty over land features and entitlement to maritime zones are legally distinct questions.
The controversy surrounding Ambassador Jing Quan’s October 15, 2026, statement adds another dimension to this dispute. His assertion that China could easily win if it used force, followed by his declaration that China would not choose force, has raised questions about the proper limits of diplomatic rhetoric. The Philippine Department of Foreign Affairs described the language as appearing to convey a thinly veiled threat of force and reminded diplomats of their obligation to exercise tact and restraint. President Ferdinand Marcos Jr. likewise said the statement sounded like a threat and warranted discussion.
This incident therefore provides an opportunity to examine how political communication can influence public perceptions, national morale, and the strategic calculations of governments. It also invites an inquiry into psychological warfare and other forms of nonmilitary influence. However, identifying a possible psychological effect is not the same as proving that a particular statement was part of an organized psychological-warfare operation.
The central question is whether the Philippines can respond firmly to intimidating or undiplomatic language without unnecessarily escalating bilateral tensions. A sound response should combine legal clarity, diplomatic accountability, public communication, regional cooperation, and a consistent commitment to peaceful dispute settlement. The objective should not be to provoke China, but to protect Philippine national interests while ensuring that diplomacy does not become an instrument of intimidation.
The legal background: What exactly overlaps?
The expression overlapping claims can obscure three separate issues.
1. Territorial sovereignty: Which state, if any, has sovereignty over a particular island or other land feature? This question is distinct from determining the maritime zones that the feature may generate.
2. Maritime entitlements and jurisdiction: What exclusive economic zone (EEZ), continental shelf, or other maritime rights does a coastal state possess under international law? Under UNCLOS, an EEZ may extend up to 200 nautical miles from applicable baselines, subject to the Convention’s provisions and any relevant overlap with another state's entitlements.
3. The legal status of historical claims: To what extent can historical rights or historic claims support maritime claims that extend beyond the entitlements recognized under UNCLOS? This was a central issue in the Philippines-China arbitration.
On July 12, 2016, the arbitral tribunal constituted under UNCLOS Annex VII issued an award addressing maritime entitlements, the legal status of features, and the lawfulness of certain Chinese activities. The award concluded that there was no legal basis for China's claims to historic rights to resources within the relevant part of the nine-dash-line area insofar as those claims exceeded the rights provided by UNCLOS. It did not decide territorial sovereignty over land features or delimit a maritime boundary between the two countries.
The Philippines regards the award as final and binding. China rejects it and maintains that it is invalid. That disagreement does not change the fact that the award is an important legal reference for analyzing the maritime dispute.

III. PSYCHOLOGICAL WARFARE: HISTORY AND FOUR STRATEGIC TECHNIQUES
1. A brief historical background
Psychological warfare is the use of communication, information, symbolism, intimidation, deception, and other methods to influence an opponent’s perceptions, emotions, confidence, and decisions. Its purpose may be to weaken an adversary’s resolve, discourage resistance, divide a population, or influence political choices without immediately resorting to physical force.
Its history is much older than modern military institutions. The ancient Chinese strategist Sun Tzu emphasized the importance of understanding an adversary, shaping circumstances, and achieving strategic objectives without unnecessary fighting. His work, The Art of War, is often discussed in connection with deception and the psychological dimensions of conflict. However, ancient strategic thought should not be treated as identical to contemporary psychological-warfare doctrine.
In modern China, the concept of the Three Warfares is particularly relevant. Defense and security scholarship describes this framework as comprising public-opinion warfare, psychological warfare, and legal warfare. These approaches concern how information, perceptions, and legal arguments can support broader strategic objectives. Sangkuk Lee's 2014 article in the Journal of Strategic Studies examines the origins, applications, and organizations associated with the concept.
Edwin S. Cochran's study of China's Three Warfares further discusses media influence, psychological effects, and the use of legal arguments in strategic competition.
These scholarly frameworks provide context for examining political rhetoric and maritime disputes. They do not, by themselves, establish that every forceful Chinese diplomatic statement is a deliberate psychological-warfare operation.
Four techniques for analyzing strategic influence
The following four points develop the ideas in your notes into an analytical framework. They are four useful categories for examining strategic influence, not an official four-part Chinese military doctrine.
1. Cognitive Influence and Perception Management
The first technique seeks to influence how an opponent interprets events. A government may frame its actions as defensive, portray its rival as provocative, or repeat a narrative until it becomes familiar to the target audience.
In the South China Sea dispute, competing descriptions of who is responsible for tensions can influence public opinion, regional diplomacy, and perceptions of legitimacy. The important question is not simply who speaks most forcefully, but whose account is supported by verifiable evidence and international law.
Application to the Jing Quan controversy: The ambassador rejected the description of China as a troublemaker and challenged the Philippine narrative. His remarks can be analyzed as competing strategic messaging, but evidence of intent would be necessary to establish a coordinated psychological operation.
2. Display of Military Strength and Deterrence
The second technique involves communicating military capability to influence another state's decisions. Military exercises, deployments, official warnings, and statements about relative strength can signal the potential costs of resistance.
Such signaling may be intended to deter conflict, but it can also create fear, encourage strategic concessions, or increase the risk of miscalculation. Its effect depends on the wording, circumstances, credibility, and perceived intentions of the actor.
Application to the controversy: The assertion that China could easily win if it used force communicates an assessment of military superiority. Although the ambassador also said China would not choose force, the initial statement could reasonably be perceived as intimidating in the context of the maritime dispute.
3. Coercive Diplomatic Messaging
Diplomatic communication can become coercive when an official links another government's choices to an implied threat, punishment, or unfavorable consequence. Such communication may seek to alter the opponent's behavior without initiating armed conflict.
The distinction between ordinary deterrence and intimidation depends on context. States may legitimately communicate their defensive capabilities, but diplomats are also expected to exercise restraint and avoid language that needlessly aggravates disputes.
Application to the controversy: The juxtaposition of an asserted ability to win by force with a declaration of peaceful intent creates an ambiguous message. Philippine officials were entitled to question that ambiguity and seek clarification through diplomatic channels.
4. Propaganda Campaigns and Information Operations
Propaganda and information operations seek to shape public attitudes through selective presentation, repetition, emotional framing, or the distribution of persuasive messages. They may involve state media, official social-media accounts, public statements, or coordinated communication networks.
The analytical challenge is to distinguish ordinary political advocacy from deceptive or coordinated manipulation. A persuasive statement is not automatically propaganda, and a disputed claim is not automatically disinformation. Claims about a campaign require evidence of its content, distribution, coordination, or intent.
Application to the controversy: The public exchange between Philippine officials and the Chinese Embassy illustrates how diplomatic disputes can expand into competing media narratives. The appropriate response is transparent communication, publication of primary documents, and independent verification rather than unsubstantiated accusations.
What is the broader lesson?
The four techniques demonstrate that modern strategic competition does not take place exclusively on the battlefield. It also occurs in public statements, media narratives, legal arguments, and the perceptions of political leaders and citizens.
Nevertheless, a rigorous analysis must distinguish a technique's possible effect from proof of a government's intention to use it. In Jing Quan's case, the available reporting supports examining the psychological and diplomatic effects of his statement. It does not establish that the statement was directed by a documented psychological-warfare campaign.

IV. PERSONAL ANALYSIS: DIPLOMATIC ACCOUNTABILITY AND THREE MECHANISMS OF PROTEST
My Personal Insights: Defending Philippine Sovereignty Without Abandoning Diplomacy
In my assessment, the most important issue raised by Ambassador Jing Quan’s statement is not whether China possesses greater military capabilities than the Philippines. The more fundamental issue is whether diplomatic communication should be used in a manner that creates an impression of intimidation when a peaceful resolution of disputes remains possible. An ambassador is not merely a spokesperson for national power; the ambassador is also a representative expected to maintain communication, facilitate understanding, and preserve the conditions necessary for peaceful engagement.
The statement that China could easily win if it used force, even when followed by a declaration of peaceful intent, was politically consequential because it was made against the background of an unresolved maritime dispute. Philippine officials were justified in seeking clarification and expressing concern about its implications. At the same time, a sound response must distinguish between a statement that is undiplomatic, a statement that may be understood as threatening, and a legally established threat or use of force. Those categories are not automatically identical.
My position is that the Philippines should respond firmly, proportionately, and through established diplomatic and legal mechanisms. National dignity does not require impulsive retaliation, and peaceful diplomacy does not require silence in the face of intimidating language. The challenge is to make the Philippine position clear while avoiding unnecessary escalation that could undermine the country's security, economic interests, or regional relationships.
1. First diplomatic option: Declare the ambassador persona non grata
The strongest personal diplomatic measure in your notes is to consider whether Ambassador Jing Quan should be declared persona non grata.
The legal basis
Article 9(1) of the Vienna Convention on Diplomatic Relations (1961) provides that the receiving state may, at any time and without having to explain its decision, notify the sending state that the head of a diplomatic mission or a member of its diplomatic staff is persona non grata. The sending state must then recall the individual or terminate the person's functions with the mission. If it refuses or fails to comply within a reasonable period, Article 9(2) permits the receiving state to refuse to recognize that person as a member of the mission.
Official legal text: Vienna Convention on Diplomatic Relations — Supreme Court of the Philippines E-Library.
What does persona non grata mean in practice?
It is a formal diplomatic declaration that the receiving state will no longer accept the individual as a member of the diplomatic mission. It is not a criminal conviction, a court judgment, or a charge that automatically establishes wrongdoing.
The Philippines does not need to prosecute an ambassador or prove a criminal offense before exercising Article 9. The provision expressly permits the declaration without the receiving state having to explain its decision. In practice, however, the government should weigh the political and diplomatic consequences carefully.
What is the proviso or limitation?
The key limitation is the distinction between the receiving state's right to declare a diplomat unacceptable and the consequences of exercising that right.
Legal authority: The Philippines may declare the ambassador persona non grata under Article 9.
Diplomatic consequence: China would be expected to recall him or terminate his diplomatic functions. China could also respond with reciprocal measures against a Philippine diplomat.
Policy consideration: Expelling the ambassador could demonstrate resolve, but it could also reduce communication channels precisely when tensions require careful management.
Article 9 does not require the Philippines to establish a criminal offense, nor does it impose a requirement to prove that the ambassador intended to threaten military action. However, the Philippines must still consider its broader obligations under international law, including the protections applicable to diplomatic personnel.
My assessment
I would treat persona non grata as a lawful option of last resort or a measure to consider if the conduct becomes persistent, serious, or incompatible with the continued exercise of diplomatic functions. The October 2026 statement warrants serious scrutiny, but the decision should be based on the totality of the ambassador's conduct, the government's diplomatic objectives, and the likely consequences—not solely on public anger.
A proportionate sequence would be to seek a formal explanation, record the government's objection, assess the response, and consider stronger measures if the conduct continues. The Philippines would retain the legal option of Article 9 throughout that process.
2. Three other diplomatic-protest mechanisms
Your handwritten notes suggest three additional approaches: economic restrictions, reconsideration of economic cooperation and development arrangements, and coalition-building with other nations. These should be considered separately because they have different legal foundations, costs, and likely effects.
Mechanism 1: Economic Measures and Trade Restrictions
Purpose: Signal political dissatisfaction through trade or economic policy.
The government could examine whether lawful, targeted economic measures are appropriate in response to serious conduct affecting national interests. However, broad restrictions on Chinese imports should not be treated as an automatic or legally uncomplicated form of diplomatic protest.
The Philippines and China have substantial economic ties. General trade barriers could increase prices for Filipino consumers, raise production costs for domestic businesses, affect exporters, and invite reciprocal measures. Trade restrictions may also engage obligations under World Trade Organization agreements and other applicable treaties.
My insight: Economic measures should be targeted, evidence-based, and legally reviewed. The government should first assess existing legal remedies, the conduct being addressed, the expected economic cost, and whether the measure is likely to achieve a clearly defined diplomatic objective. A blanket import ban undertaken simply to express anger could harm Philippine interests more than it influences Chinese policy.
Mechanism 2: Review of Development Projects, Funding, and Cooperation Agreements
Purpose: Reassess the terms and strategic value of bilateral cooperation.
The Philippines could review proposed or existing development projects, financing arrangements, infrastructure agreements, or other bilateral initiatives where a genuine legal, security, financial, or public-interest concern exists. This may include reviewing contractual safeguards, transparency, procurement procedures, debt exposure, and compliance with Philippine law.
However, abruptly withdrawing support from projects or suspending funding merely to punish an ambassador's remarks may breach contractual obligations, trigger compensation claims, waste public resources, or harm Filipino communities that depend on the projects.
My insight: The proper approach is not automatic cancellation, but a documented review of national interest. Where the review identifies legitimate concerns, the government should use the termination, suspension, renegotiation, or dispute-resolution provisions of the relevant agreements. Diplomatic displeasure should not be used as a substitute for evidence or sound economic governance.
Mechanism 3: Coalition-Building and Multilateral Diplomatic Pressure
Purpose: Strengthen the Philippines' position through coordinated diplomacy.
The Philippines could consult ASEAN partners and other states that support peaceful dispute settlement and respect for international law. It could share verified evidence of maritime incidents, seek joint statements where consensus is possible, raise concerns through appropriate regional and international forums, and strengthen cooperation on maritime safety and crisis communication.
The July 2026 joint statement marking the tenth anniversary of the South China Sea arbitral award illustrates how multiple governments can reaffirm the importance of UNCLOS and the award's legal significance.
My insight: Coalition-building is particularly valuable because it places the dispute within a wider framework of international law rather than presenting it solely as a bilateral confrontation between a smaller state and a larger power. The goal should be to build durable support for legal principles, transparency, peaceful settlement, and regional stability—not to manufacture an anti-China bloc.
Comparing the three mechanisms
Mechanism | Principal advantage | Principal risk | Recommended approach |
|---|---|---|---|
Economic restrictions | Can signal serious displeasure | Higher prices, retaliation, legal disputes | Targeted and legally reviewed |
Review of projects and agreements | Protects public interest and national security | Contractual costs and harm to local beneficiaries | Evidence-based review |
Coalition-building | Adds diplomatic weight and legitimacy | Differences among partners may limit consensus | Sustained, rules-based cooperation |
These three mechanisms do not have equal legal status or identical effects. Economic measures and project suspensions require examination of applicable law and contractual commitments. Coalition-building, by contrast, can strengthen diplomatic support without necessarily imposing immediate economic costs.
The Philippines should therefore select measures according to the conduct at issue, the desired outcome, and the likely consequences for the country.
3. The legal and diplomatic distinction: Protest, retaliation, and accountability
A diplomatic protest should not be confused with a criminal charge or a finding that a state has violated international law.
In my view, the Philippines should distinguish among three objectives:
Expressing formal objection: A diplomatic protest records the government's opposition to a statement or action and requests that the conduct not be repeated.
Securing accountability: A formal explanation, consultation, or other diplomatic measure can clarify the ambassador's meaning and communicate the standards expected of diplomatic representatives.
Protecting national interests: Legal proceedings, regional diplomacy, security cooperation, and appropriate economic reviews can address the wider maritime dispute without making the ambassador's remarks the sole measure of Philippine policy.
Article 9 of the Vienna Convention gives the Philippines a clear legal option concerning diplomatic accreditation. However, the legal availability of a measure does not automatically establish that it is the wisest policy in every circumstance.
The central policy question is whether expulsion would advance the Philippines' objectives more effectively than continued engagement accompanied by firm, documented objections. That is a decision for the Philippine government, informed by national security assessments, diplomatic consultations, and the anticipated consequences.
4. My proposed diplomatic response
My proposed response is a firm but calibrated diplomatic strategy. First, the Philippines should maintain a clear record of the ambassador’s statement and request an explanation through appropriate diplomatic channels. Second, it should communicate that remarks suggesting military superiority or the possible use of force are unhelpful and risk undermining mutual trust. Third, the government should continue defending Philippine maritime rights through international law, transparent documentation, and constructive cooperation with regional partners.
If further conduct demonstrates a persistent disregard for diplomatic responsibilities, the Philippines may consider stronger measures, including declaring the ambassador persona non grata under Article 9 of the Vienna Convention on Diplomatic Relations. The government should also evaluate the feasibility of economic or contractual measures only after determining their legal basis, proportionality, and likely effects on Filipino citizens.
Finally, the Philippines should continue strengthening partnerships with ASEAN members and other states that support peaceful dispute settlement and respect for international law. This approach preserves national dignity without making escalation an end in itself. The purpose of diplomacy is not merely to express anger, but to protect national interests and create conditions in which disputes can be managed without violence.
Conclusion: National Dignity Through Strategic Restraint
The controversy surrounding Ambassador Jing Quan's October 2026 statement demonstrates how a few sentences can have consequences beyond the immediate exchange between a diplomat and reporters. In the context of the South China Sea dispute, rhetoric about military superiority can intensify public concern, complicate diplomatic engagement, and raise questions about the appropriate use of diplomatic authority.
The history of strategic influence and the modern framework of the Three Warfares offer useful perspectives for analyzing the relationship between information, perception, and power. Yet these perspectives must be applied carefully. A statement may have an intimidating psychological effect without proving that it was part of a coordinated psychological-warfare campaign.
For the Philippines, the more enduring challenge is to combine diplomatic firmness with legal precision. Declaring an ambassador persona non grata is a lawful option, but it should be assessed alongside formal protest, economic and contractual reviews, and coalition-building. Each measure should be evaluated according to its legal basis, effectiveness, and consequences for the Filipino people.
My final insight is this: Philippine sovereignty is best defended not through rhetoric alone, but through a combination of legal clarity, credible national institutions, strategic communication, and principled diplomacy. A peaceful response is not a sign of weakness, just as a forceful statement is not proof of strength. The Philippines should remain firm in defending its rights while ensuring that every diplomatic action serves the long-term interests of the nation.
