One answer lies in the fact that China’s FDI policy over the past 30 years has crowded out Chinese investors from high-return projects, forcing them to settle for less lucrative projects. But there are still potential investors who cannot find any suitable investment opportunities in China, generating excess resources, which in turn are invested in US government securities.
一个答案，过去30年来，中国的FDI政策将中国投资者挤出了高回报项目，迫使他们投资于低回报项目。但仍然有不少潜在投资者在中国找不到任何合适的投资机会，他们手里握着过剩的资源，只能投资于美国国债。
