Asia's premier defense summit opened in Singapore with regional officials confronting twin anxieties: China's expanding military footprint and mounting uncertainty about whether the United States will honor its longstanding security commitments in the Indo-Pacific.
The Shangri-La Dialogue brought together defense ministers and officials from across the region, including Australia, as questions swirl about American reliability following recent diplomatic overtures between Washington and Beijing that have left traditional U.S. partners unsettled. Vietnam's leader To Lam delivered the keynote address, warning that global interconnectedness means regional flashpoints can rapidly destabilize economies and societies far beyond their immediate geography.
Strategic Competition and the Call for Restraint
Lam told an audience that included U.S. Defense Secretary Pete Hegseth and a high-level Chinese delegation that "Recent tensions along strategic maritime routes in the Middle East remind us that a single flashpoint can rapidly disrupt trade, energy supplies, logistics and social economic life across the globe." The Vietnamese leader described the region as "the world's most dynamic center of growth, but also a theater of intense strategic competition, a region defined by vital maritime routes, yet fraught with risk."
Lam emphasized that the region seeks "neither the mere presence nor absence of any major power, what it seeks is responsible commitment." He added, "We recognize that competition is an enduring reality of international relations, but competition must be bound by law, guided by transparency and exercised with restraint."
Vietnam's Delicate Balancing Act
Lam has consolidated his power in Vietnam this year, becoming both Communist Party general secretary and president of the strategically important Southeast Asian nation, departing from its tradition of shared leadership. Vietnam faces competing maritime claims with Beijing that have led to confrontations, while also being heavily tied economically to China, its biggest two-way trade partner. The United States is Vietnam's largest export destination and has been seeking to make diplomatic inroads and expand defense contracts to pull some of that market away from Hanoi's traditional partner, Russia.
Recently leaked documents showed that even after elevating relations with Washington to the highest diplomatic level, Vietnam's military remained skeptical of American intentions and had taken steps to defend against a possible American "war of aggression." At a meeting with Lam and Vietnam's defense minister ahead of Lam's speech, Hegseth "applauded Vietnam's rapid military modernization, which will strengthen Vietnam's ability to defend its sovereignty and our shared interests," according to a Pentagon statement.
Hegseth's Message and Trump's Taiwan Ambivalence
Hegseth was due to speak on Saturday morning and was making his second appearance at the event. Last year in Singapore, Hegseth said "the threat China poses is real, and it could be imminent," and that its military was "rehearsing for the real deal." He said Washington would bolster its defenses to counter what the Pentagon sees as rapidly developing threats, particularly in China's aggressive stance toward Taiwan.
Hegseth's speech comes about two weeks after U.S. President Donald Trump visited Chinese leader Xi Jinping in Beijing, where Xi warned that the two countries could clash over Taiwan if the issue was not handled properly. After the meeting, Trump called Xi a "great leader" and said they were going to have a "fantastic future together." Trump also raised questions about Washington's willingness to defend Taiwan, calling a new $14 billion arms package that he has yet to greenlight "a very good negotiating chip for us" with China.
China claims the self-governing democratic island as its own, and Xi has not ruled out using force to take it. The U.S. supplies Taiwan with modern aircraft, missiles and other weapons to help it defend itself, while following a policy of "strategic ambiguity" on whether it would intervene militarily if China attacked. Trump has shown greater ambivalence toward Taiwan than his predecessors, fueling speculation about whether he could be persuaded to dial back American support. Hegseth's speech was to focus on the military's "common-sense approach to safeguarding U.S. vital national interests in the Indo-Pacific," according to the Pentagon.
Why This Matters:
The summit reveals deep anxieties among America's regional partners about whether democratic nations can rely on U.S. security guarantees at a moment when authoritarian pressure is intensifying. Trump's willingness to treat Taiwan's defense as a bargaining chip rather than a matter of democratic principle undermines decades of collective security architecture that has protected smaller nations from coercion. For countries like Vietnam that face direct territorial disputes with Beijing, American ambivalence creates dangerous uncertainty about whether international law and multilateral frameworks will be enforced or abandoned to great-power deal-making. The outcome will determine whether the region's future is shaped by rules-based cooperation that protects sovereignty and human rights, or by unrestrained strategic competition that leaves vulnerable populations and democratic societies exposed to authoritarian expansion.
