Book excerpt: Examines foreign direct investment (FDI) in the United States, the national security concerns associated with this investment, and treatment of these concerns under US policy. This book asks whether the Committee on Foreign Investments in the United States (CFIUS) process can be improved and answers in the affirmative.Does foreign ownership of American businesses pose a threat to the United States (like the abortive attempt by CNOOC, a Chinese company, to purchase Unocal during the summer of 2005)? This important new book examines foreign direct investment (FDI) in the United States, the national security concerns associated with this investment, and treatment of these concerns under US policy. It asks whether the Committee on Foreign Investments in the United States (CFIUS) process can be improved and answers in the affirmative. The book starts by looking at the review process for foreign takeovers of US firms (including a historical review), looks at the economic and political impact on the United States of foreign direct investment, takes a detailed look at issues relating to FDI posed by the rise of China as an economic and geopolitical power and finally suggests some changes to the Exon-Florio process.
