The World Health Organization said it’s working with Taiwanese health experts after an interview went viral in which a senior official appeared to hang up on a reporter who asked about the island’s membership status in light of the COVID-19 outbreak.

In the segment aired by Hong Kong broadcaster RTHK, a journalist asked Bruce Aylward, who helped lead a WHO mission to China’s Wuhan, if the organization would consider giving Taiwan membership. The footage showed him saying he couldn’t hear properly, and asking the reporter to skip to the next question. It then showed the line disconnecting after the reporter said she’d like to hear more about Taiwan.

Later when the call was reconnected, the presenter asked him to comment on Taiwan’s progress in containing the virus. Aylward replied that all areas of China have done well and wished Hong Kong luck in its efforts.
