The Biden administration attaches great importance to the issue of climate change.After taking office,it sets out to restart US climate cooperation with China,which had stalled during the Trump administration.To this end,the Biden administration has reinvigorated the policy agenda of climate governance at home and resumed the implementation of global climate governance obliga-tions at the international level,including bilateral and multilateral cooperation with China on climate change.The resumption of US climate cooperation with China is a result of the climate philosophy of President Biden and his policy team.It is driven by domestic political factors such as the traditional climate position of the Democratic Party,pressure from the progressive members within the party,and influence of domestic interest groups.It also serves the Biden ad-ministration's overall China policy.However,such resumption has been difficult owing to the paradigm of US strategic competition with China.There are multiple restrictions like constant constraints from the Republican Party which is tougher on China,the gap between China and the US on the responsibility sharing for global climate governance and the dilemma between"climate first or containing China first".
