中美两国最高领导人会晤意味着未来十年基于中美“战略互信”基础上构建起来的包括经济、贸易、投资在内的双边战略框架将有望成形。尽管中美双边贸易流动为全球规模最大,但双边投资规模并不大而且直接投资“不对等”。截至2011年末,美国对华实际投资676亿美元,而同期中国对美国投资不到300亿美元。从排名上看,美国是中国最大的外来直接投资国,而中国的直接投资在美国仅排第25位,中国对美投资总量占美国吸收外资总量不到1%。金融危机后为缓解长期以来由于贸易顺差导致的外汇储备激增和资产安全,中国主权财富基金大规模投资海外,推动“资本出海”。然而这在一定程度上加剧了美国对“战略性投资”与“国家资本主义”的警惕,常常遭遇美国政府外资审查委员会基于“国家安全”考虑的阻碍,并限制 The summit meeting between the leaders of China and the United States means that the bilateral strategic framework including economic, trade and investment built on the basis of the Sino-U.S. Strategic mutual trust will be expected to shape the next decade.

As of the end of 2011, the U.S. actually invested 67.6 billion U.S. dollars in China, while China invested less than 30 billion U.S. dollars in the U.S. in the same period. In terms of rankings, the United States is China’s largest foreign direct investment country, while China’s direct investment ranks only 25th in the United States. China’s total investment in the United States accounts for less than 1% of the total foreign investment in the United States. After the financial crisis, in order to ease the surge in foreign exchange reserves and asset security that have long been caused by trade surpluses, China’s sovereign wealth funds invested heavily overseas to promote “capital going to sea.” However, this has exacerbated the vigilance of the United States to “strategic investment” and “national capitalism” to a certain extent and has often been hindered by the U.S. government’s foreign investment examination committee based on the consideration of “national security”
