In response to U.S. Secretary of Health and Human Services Azar's visit to Taiwan in the near future, the spokesperson of the National Health Commission said on August 6 that the Taiwan issue is China's internal affairs and no external forces are allowed to interfere. China urges the US to abide by the one-China principle and the provisions of the three Sino-US joint communiqués, and immediately revoke the wrong decision of the head of the US health administration to conduct official exchanges with Taiwan. China and the United States should work together to develop constructive health cooperation to safeguard the health and well-being and health security of the people of both countries and the world.
