On 5 May 2020, Peters expressed support for Taiwan rejoining the World Health Organization during a press conference. Peter's announcement was welcomed by the Taiwanese Government, which reiterated its friendship with New Zealand. The New Zealand Government subsequently announced its support for Taiwan's bid to join the WHO, putting NZ alongside Australia and the United States who have taken similar positions. In response, the Chinese Embassy issued a statement reminding Wellington to adhere to the One China Policy. In response, Peters told the Chinese Ambassador to "listen to her master", and stated that New Zealand should follow Taiwan's example of making the wearing of face masks compulsory. Peter's remarks were criticised by Chinese Foreign Ministry spokesperson Zhao Lijian, who warned that they violated the One China Policy and would hurt China-New Zealand relations. Peters has stood by his remarks.
