2019 was the first year for China to build a comprehensive strategic partnership with eight Pacific island countries，it was also a crucial year for China to win diplomatic victories in the South Pacific region. In October 2019，the third “China-Pacific Island Countries Economic Development and Cooperation Forum” was successfully held. Under the framework of jointly building “Belt and Road Initiative”，China and Pacific island countries carried out extensive and in-depth cooperation and exchanges in trade and investment，infrastructure，tourism，and climate change. Since the outbreak of the COVID-19 epidemic in 2020，China and Pacific island countries have innovated communication methods and exchanged anti-epidemic information，giving “Belt and Road Initiative” a new historical mission of “Healthy Road”. Affected by the COVID-19 epidemic，the economic and social development of Pacific island countries faces serious challenges. China，which takes the leading role in fighting the COVID-19 epidemic，is using its advantages in infrastructure and supply chain to help Pacific island countries tackle their difficulties. In the future，under the framework of South-South cooperation，China will further deepen the development relations with Pacific island countries，making South Pacific a shining spot in China’s large periphery diplomacy.
