Fresh uncertainty is hanging over US-China relations after President Donald Trump revived allegations that China sought to influence American elections, injecting new political tension into a relationship that had only recently shown signs of stabilising.
Trump's primetime address on Thursday shifted attention away from recent diplomatic progress and back towards one of the most contentious issues between Washington and Beijing. The renewed claims arrive at a particularly sensitive moment, with a proposed summit between Trump and Chinese President Xi Jinping expected in September but not yet officially confirmed by Beijing.
