BEIJING — China always puts the safety and efficacy of COVID-19 vaccines first, a spokesperson for the annual session of the country's top political advisory body said on March 3.

China's technical standards of application for market rollout and conditional market approval meet requirements of the World Health Organization and a number of developed countries, said Guo Weimin, spokesperson for the fourth session of the 13th National Committee of the Chinese People's Political Consultative Conference, at a press conference.

China's COVID-19 vaccines have been approved for use in many other countries, with some foreign leaders taking the lead in vaccination, Guo added.
