Joe Biden’s decision to expand the US investigation into the origins of the Covid-19 pandemic, with one intelligence agency leaning towards the theory that it escaped from a Wuhan laboratory, has opened a new divide in his administration’s already tense relationship with China.

Biden said on Thursday that he would publish the results of the 90-day inquiry, which has made a priority for the intelligence agencies. The move represents a dramatic turnaround from the administration’s policy until now of leaving the investigation to the World Health Organization.

The US on Thursday called on the WHO to carry out a second phase of its investigation into the origins of the coronavirus, with independent experts given full access to original data and samples in China.
