Over the past three years, the Chinese government has committed to protecting the lives and health of the Chinese people, contributed its best efforts to the international battle against the virus, and played a crucial role in the world's post-COVID-19 economic recovery. China continues to share genetic sequences of new viruses in China with the WHO and GISAID, and makes positive contributions to vaccine and drug development.
