The new US administration of President Joe Biden has clearly committed to a "free and open Indo-Pacific" (FOIP), and cooperation through the QUAD has been deepened significantly by the holding of summit meetings and the agreement and implementation of concrete cooperation. The United States, the United Kingdom and Australia have launched AUKUS as a new security framework. Faced with the challenges of dealing with the military coup in Myanmar and the coronavirus pandemic, ASEAN has not made notable progress in its efforts to put the ASEAN Outlook on the Indo- Pacific (AOIP) into practice, while external actors such as the United States and China have stepped up their approaches to ASEAN. In the economic realm, it has been confirmed that the Regional Comprehensive Economic Partnership (RCEP) will come into effect in January 2022, and China and Taiwan have applied to join the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP).
