Primary health care (PHC) is the most effective way to improve people's health and well-being, and primary care services should act as the cornerstone of a resilient health system and the foundation of universal health coverage. To promote high quality development of PHC, an International Symposium on Quality Primary Health Care Development was held on December 4-5, 2023 in Beijing, China, and the participants have proposed and advocated the Beijing Initiative on Quality Primary Health Care Development.
