From the Overview: "The growing prominence of foreign direct investment (FDI) raises questions about its costs and benefits to the U.S. economy. Traditionally, the United States has supported a rules-based and open investment environment internationally in order to promote economic growth and advance other policy objectives. U.S. investment policy includes negotiating rules, disciplines, and market access commitments concerning FDI in trade agreements and Bilateral Investment Treaties (BITs) and administering investment promotion programs. It also involves reviewing certain proposed inbound FDI transactions for U.S. national security implications. FDI is a part of U.S. trade policy, given that it is a major driver of trade and plays a role in facilitating global supply chains."
