拜登任期已经过半，美国对华战略从酝酿制定转入落实和执行。拜登政府提出“投资、协同、竞争”的对华战略框架，并陆续通过发布《美国印太战略》、《国家安全战略》和《2022年国防战略》等官方文件将其固化。在“战略竞争”思维的定式下，美国延续对华打压态势，中美博弈迈向深化：在台湾问题上，美国持续虚化、掏空一个中国原则，双边关系的政治基础遭受严重侵蚀；在经贸科技领域，美国延续对华“选择性脱钩”，中美制裁与反制裁日趋升级；在地缘政治领域，美国意图“形塑中国周边环境”，两国之间的围堵与反围堵仍在继续。尽管中美在多个领域矛盾显著，但仍未放弃通过沟通寻求共识，管控分歧，并尝试开启新的缓和“窗口”。
Halfway through President Biden’s first term，the US strategy toward China has shifted from planning to implementation. The Biden administration has released a strategic framework of “invest，align，compete” toward China，and solidified it by Indo-Pacific Strategy，the National Security Strategy and the National Defense Strategy. Under a competitive mindset，competition is getting fiercer. The US has hollowed out the one-China principle and severely eroded the bilateral political foundation. With the “selectively decoupling” from China，sanctions and anti-sanctions from both sides have intensified. To shape the strategic environment around Beijing，the US have tried to contain China through military means and ends. Although China and the US are at odds in many areas，both sides have not given up seeking consensus through communication，managing differences，and trying to open a new “window” for detente.
