Once hardly noticeable, Chinese investments in U.S. companies are now rising sharply. Cumulative Chinese investments in U.S. companies remain modest compared to those of other major countries. However, a combination of "push and pull" factors are moving China's annual investment levels closer to levels consistent with China's current economic stature. The Chinese government has made a conscious decision to diversify its foreign currency assets into hard assets. This had led to the creation of sovereign wealth funds that make portfolio investments in U.S. equities, private firms, and real estate. The Chinese government has also altered is policy toward foreign direct investment (FDI). Whereas it previously encouraged investments almost exclusively toward energy and resource acquisition in developing countries, it now also encourages investments in advanced countries. The government's goals for these investments include securing energy and mineral resources and acquiring advanced technologies in industries where China wishes to leapfrog existing competitors. This book provides an overview of select analyses on Chinese investments in the U.S. economy, with a focus on the economic benefits and policy challenges.
