After World War II, in order to obtain better growth performance from the large foreign exchange reserves or public funds, several new financial institutions in East Asia and oil-producing countries in the Middle East started to have their governments establishing the Sovereign Wealth Fund. The Sovereign Wealth Fund has attracted wide attention as their scales rapidly expanded in recent years. The fund scale increased by 18% in 2007, as compared to 2006, and reached USD 330 billion. It is estimated that the funds will exceed USD 12 trillion in 2015. The large capital of the Sovereign Wealth Fund appeared especially important in the 2008 global financial crisis caused by the subprime mortgage crisis in the U.S, and became the lifesaver to countries and companies on the verge of bankruptcy. Basically, from the perspective of international political economics, the development of the Sovereign Wealth Fund conforms to the Interdependency Theory and the Process Theory in the globalization theories. However, on the other hand, the rapid development of the Sovereign Wealth Fund has led to several problems, which not only influence international financial markets, but also trigger political and economical risks under information asymmetry that leads to suspicions of other countries. In particular, China, the world's largest holder of foreign exchange reserves, established the Sovereign Wealth Fund in 2007, as its socialist government structure and authoritative dictatorship governance, as well as the increasingly evident international political and economical strength, have aroused international concerns. However, whether it will make the ”Statist Theory” that stresses commercialism becoming a mainstream deserves further observations.
