Since late 2008, relations between the United States and South Korea have been arguably at their best state in decades. By the middle of 2010, in the view of many in the Obama Administration, South Korea had emerged as the United States' closest ally in East Asia. This book examines U.S.-South Korea relations; the EU-South Korea Free Trade Agreement and its implications for the United States; the issues surrounding the U.S.-South Korea beef dispute; the Kaesong North-South Korean Industrial complex and major policy considerations for the U.S. and South Korean co-operation in the world nuclear energy market.
