SINGAPORE — Defense Secretary Pete Hegseth told Asia's premier security summit Saturday that Washington will no longer foot the bill for wealthy partners, pressing allies to spend more on their own defense a day after Vietnam's leader warned the gathering that a single flashpoint can rapidly disrupt global trade and energy supplies.

The consecutive-day messages at the Shangri-La Dialogue captured the central tension confronting the Indo-Pacific: a Trump administration determined to confront China's military buildup while simultaneously demanding allies pay more and hedging on Taiwan, a posture that has left regional capitals recalculating how much American protection they can count on.

Spending demand

Hegseth, making his second appearance at the Singapore conference, told delegates that the cost-sharing era of American alliances was finished. "The era of the United States subsidising the defence of wealthy nations is over," he said. "We need partners, not protectorates. We don't have a strong alliance unless everyone has skin in the game. No freeloading."

He paired the demand with a sharper warning about Beijing's intentions. "There is rightful alarm regarding China's historic military buildup and the expansion of its military activities in the region and beyond," Hegseth said. A Pacific tilted toward any single power, he added, "would unravel the regional balance of power."

Hanoi's caution

The day before, Vietnamese leader To Lam delivered the keynote to an audience that included Hegseth and a senior Chinese delegation, using the Strait of Hormuz crisis to argue that local disputes can quickly become global ones. "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," Lam said.

Lam, who has consolidated power this year by holding both the Communist Party general secretary and presidential posts, framed the region as caught between opportunity and risk. "This is 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," he said. He pressed Washington and Beijing alike to operate within international law, arguing that competition "must be bound by law, guided by transparency and exercised with restraint."

Taiwan ambiguity

Hegseth's line on China contrasted with signals from the White House. The speech came roughly two weeks after President Trump met Chinese leader Xi Jinping in Beijing, where Xi warned that the two countries could clash over Taiwan if the issue was mishandled. Trump emerged from those meetings calling Xi a "great leader" and describing a $14 billion arms package for Taipei, which he has yet to approve, as "a very good negotiating chip for us" with China.

On Taiwan, Hegseth offered continuity without commitment. "Those decisions will depend on the president and the nature of that relationship," he said. "There's been no change in our status."

Skepticism in the room

The gap between American rhetoric and American reliability is not lost on the host region. Leaked Vietnamese documents disclosed this year showed that Hanoi's military, even after upgrading ties with Washington to the highest diplomatic level, remained wary of U.S. intentions and had drafted contingency plans against a possible American "war of aggression." Vietnam's largest export market is the United States; its largest two-way trading partner is China.

Lam's own formulation cut closer to the doubts surrounding Hegseth's pitch. "What the region seeks is nether the mere presence nor absence of any major power, what it seeks is responsible commitment," he told the hall.

Bilateral postscript

At a bilateral meeting before the keynote, Hegseth "applauded Vietnam's rapid military modernization," according to a Pentagon statement, and pledged to deepen cooperation. Whether allies read his Saturday address as a renewed American commitment or a transactional offer will shape the coming year of Indo-Pacific diplomacy, with a $14 billion Taiwan weapons package, an unresolved Hormuz ceasefire and the aftermath of Trump's Beijing visit all waiting on the same desk in Washington.
