Following the inauguration in January 2021, the Biden administration has adopted his predecessor's anti-China policy and maintained the specific concerns on issues related to China and the future dynamics in the Indo-Pacific region. The Biden administration's foreign policy is characterized by the feature of multilateral diplomacy which values the significance of U.S. allies and partners and emphasizes the importance of multilateral cooperation on issues of international concern. Multilateral diplomacy has been seen as a principle followed by U.S. decision-making elites to address the so-called China threat and affairs related to the Indo-Pacific region. Notably, the Biden Administration's Indo-Pacific strategy can be further understood by security and economic dimensions. To maintain the free and open Indo-Pacific order and balance China's increasing influence in this critical region, the Biden administration has deepened U.S. ties with its Quad allies and partner and constructed the particular security establishment with Australia and the United Kingdom-namely the AUKUS. Furthermore, it has prompted the Indo-Pacific Economic Framework (IPEF) to keep the rules and norms drafted by the U.S. rather than its Chines counterpart.
