Washington has broken with decades of diplomatic convention after President-elect Donald Trump spoke by telephone with Tsai Ing-wen, the president of Taiwan, on Friday. The call, confirmed by both the Trump transition team and the Taiwanese government, marks the first direct communication between a US president or president-elect and a Taiwanese leader since the United States shifted diplomatic recognition from Taipei to Beijing in 1979.
The move has drawn immediate criticism from Beijing, which considers Taiwan a breakaway province and prohibits official contact between foreign governments and Taiwanese leaders. China’s foreign ministry issued a statement expressing “strong dissatisfaction” and warning that the call could damage US-China relations. “The Chinese government firmly opposes any form of official contact between Taiwan and the United States,” the statement read.
The British government, which maintains a robust One China policy, swiftly reaffirmed its position. A Foreign Office spokesperson told the BBC: “The UK’s position on Taiwan is clear and consistent. We do not recognise Taiwan as a state. We maintain a One China policy and have no official relations with Taiwan.”
Trump’s decision to take the call has been characterised by analysts as a deliberate break from the diplomatic norms that have governed US-Taiwan relations since the Taiwan Relations Act of 1979. That act, while allowing unofficial ties, explicitly bars official exchanges. Trump’s transition team offered no explanation for the call, but the president-elect later tweeted: “The President of Taiwan called me today to congratulate me on my victory. Very nice!”
The call has raised questions about the future of US-China trade relations and regional stability in the Asia-Pacific. China is the United States’ largest trading partner, and the Trump administration had already signalled a harder line on trade and security issues.
Beijing has used the incident to reiterate its sovereignty claims. “Taiwan has always been an inalienable part of China since ancient times,” the foreign ministry said. “Any attempt to challenge this fact is doomed to fail.”
The Taiwanese government, for its part, described the call as a “normal exchange of congratulations” and said Tsai had expressed hope for closer ties with Washington. However, the move is likely to embolden pro-independence voices in Taiwan while increasing Beijing’s determination to isolate the island diplomatically.
The episode also places Britain and other Western powers in a delicate position. The UK, which has invested heavily in the bilateral relationship with China, particularly in trade and investment, is careful to avoid any perception of deviation from the One China policy. The Foreign Office’s immediate reaffirmation underscores the importance London places on maintaining stability with Beijing.
Strategic analysts in London note that the call could have wider ramifications for Western alliances. “The UK is dependent on a stable US-China relationship for its own economic interests,” said a senior fellow at Chatham House. “Any disruption in that dynamic will have knock-on effects for Britain and Europe.”
As the Trump administration prepares to take office, the incident serves as an early indicator of a more transactional, less rules-based approach to foreign policy. The traditional diplomatic architecture that has underpinned US-China ties for nearly four decades may be under threat.
Beijing has so refrained from public threats of retaliation, but it has private warned of consequences. The Chinese ambassador to the United States cautioned that the call “could affect the overall atmosphere of US-China relations”.
For now, the ball lies in the hands of the incoming administration. Whether the call was a one-off gesture or the beginning of a new policy towards Taiwan will determine the trajectory of the most consequential bilateral relationship of the 21st century.
