BEIJING, Feb. 10 (AFP) - A member of the WHO mission to China exploring the origins of the coronavirus pandemic took a swipe at US intelligence on the issue, after the State Department cast doubt on the transparency of their probe.

President Joe Biden "has to look tough on China", expert Peter Daszak said in a tweet as the mission ended, adding: "Please don't rely too much on US intel: increasingly disengaged under Trump & frankly wrong on many aspects."
