China's Vaccine Diplomacy and Its Implications for Global Health Governance.

The COVID-19 pandemic has wreaked havoc on global economy and human communities. Promoting the accessibility and affordability of vaccine via diplomacy is the key to mitigating the pandemic crisis. China has been accused of seeking geopolitical objectives by launching vaccine diplomacy. The definition of vaccine diplomacy is neutral by nature. China's vaccine diplomacy is based on its holistic approach to national security and the importance China attaches to the "Belt and Road" Initiative. With a whole-of-government approach on both the bilateral and multilateral levels and marketization of vaccines, China's vaccine diplomacy has immense implications for global health governance, in that it helps to narrow the global immunization vaccination gap and to promote human-right-based approach to global health governance. However, the sustainability of China's vaccine diplomacy is questionable because of the Sino-American geopolitical competition and doubts over the efficacy of China's vaccines. The escalation of power rivalry between China and the U.S. and the concerns over the efficacy of China's vaccines forebode the gloomy future of China's vaccine diplomacy.
