US President Donald Trump said his hard-fought trade deal with China was now of secondary importance to the coronavirus pandemic and he threatened new tariffs on Beijing, as his administration crafted retaliatory measures over the outbreak. Mr Trump's sharpened rhetoric against China reflected his growing frustration with Beijing over the pandemic, which has cost tens of thousands of lives in the US alone, sparked an economic contraction and threatened his chances of re-election in November. Mr Trump also made clear that his concerns about China's role in the origin and spread of the coronavirus were taking priority for now over his efforts to build on an initial trade agreement with Beijing that long dominated his dealings with the world's second-largest economy.
