Is the US dialling down its support for Taiwan?

A year ago, US-China relations reached one of their lowest points when Donald Trump announced his Liberation Day tariffs. The US president made some concessions when he met Xi Jinping a few months later. And the White House yielded more ground in the run-up to Trump's visit to Beijing. It suspended a $14 billion arms sale to Taiwan, which China claims as its sovereign territory. But that did not stop President Xi from calling Taiwan 'the single most important issue' in relations with the US. Could a dispute over the territory lead to conflict between Beijing and Washington?
