Two members of the international team had already set out on their journey to China. One has now turned back and the other is in transit in a third country, emergencies chief Mike Ryan said. However, he added: “We trust and hope that is just a logistic and bureaucratic issue that can be resolved very quickly.”
Ahead of the trip, Beijing has been seeking to shape the narrative about when and where the pandemic began, with senior diplomat Wang Yi saying “more and more studies” showed that it emerged in multiple regions. Ryan has previously called this “highly speculative”.
China has dismissed criticism of its handling of early cases that emerged in late 2019, although some including U.S. President Donald Trump have questioned Beijing’s actions during the outbreak.
Washington, which has announced plans to leave the WHO, has called for a “transparent” investigation and criticised its terms under which Chinese experts conducted the first phase of research.
