The year of 2022 saw Southeast Asian countries host successive diplomacy summits. Cambodia，Indonesia and Thailand have successfully hosted three large-scale and high-level international conferences，including the East Asia Summit，the G20 Summit and the APEC Economic Leaders’ Meeting in November 2022，through several rounds of diplomatic efforts within this year. This phenomenon reflected that ASEAN countries hold on to self-unity and ASEAN centrality，as well as seek strategic autonomy，achieving remarkable results. Firstly，they promote bilateral relations through multilateral cooperation，pushing China-U.S. relationship to break the ice. Secondly，they promote global governance through regional governance，driving the global governance focus orientation. But at the same time，these Summits also have some limitations in terms of speed，agenda setting，representativeness and sustainability. The phenomenon of “Summit year” of ASEAN reflects the flexibility and inclusiveness of ASEAN among major powers，which holds the characteristic of advocating cooperative dialogue. And the recognition of major powers further enhances its pivotal status. In the future，China should continue to respect and recognize ASEAN centrality and help ASEAN develop its strategic autonomy in more issue areas. We should jointly build a regional framework centered on ASEAN，maintaining the development direction of regional cooperation，peace and common prosperity.
