Donald Trump has declared his intention to speak directly with Taiwan’s President Lai Ching-te, a move that would shatter more than four decades of diplomatic convention and risk a severe confrontation with Beijing. The US president told reporters on Thursday that he would “work on that Taiwan problem”, adding: “I speak to everybody.” Since 1979, when Washington recognised the People’s Republic of China and severed formal ties with Taipei, no sitting US president has spoken with a Taiwanese leader. Trump’s remarks, made as the White House considers a $14 billion arms package for the island, have drawn an immediate and sharp response from China.

Viewed from Beijing, the prospect of a presidential phone call crosses a clear red line. Chinese foreign ministry spokesman Guo Jiakun reiterated that Beijing opposes any official exchanges between Washington and Taiwan, and described the island as an inalienable part of China. The timing is particularly sensitive: only days after Trump concluded a summit with President Xi Jinping, analysts in London note that such a call would undo any goodwill generated and inject “turbulence” into the relationship. Trump’s framing of Taiwan as a “problem” and arms sales as a “bargaining chip” in dealings with China has also unsettled observers — Taipei being described in language that echoes Beijing’s own narrative.

For its part, Taipei has signalled openness. Taiwan’s foreign ministry stated that President Lai would be “happy to discuss these matters” with Trump, while emphasising a commitment to maintaining stability in the Taiwan Strait. Yet the island’s leadership must navigate a delicate path: welcoming US attention while avoiding provocation. The US envoy to Taiwan, meanwhile, has sought to reassure the island that Washington’s long-standing commitments remain unchanged, even as Trump’s transactional tone raises questions about reliability.

Looking ahead, the probability of an actual call remains contested. Analysts caution that Trump’s remarks may be bluster, but even a shift in tone carries risk. Any direct contact would not only inflame Beijing but could complicate the careful balancing act that has allowed the US to maintain ties with both China and Taiwan. As the arms sale decision unfolds, the episode exposes the fragility of the status quo — and the consequences of a president who prides himself on breaking norms. For Washington, Taipei, and Beijing alike, the coming days will test whether diplomatic precedent can survive political improvisation.
