Over the past two years, the EU's economic protectionism has risen again. Both its official statements and policies show some new trends and characteristics. The basic cause of these latest trends is the relative decline in the overall strength of the EU, especially in regard to the ongoing impact of the financial and debt crisis on its economic, political and social fields. In general, the EU is likely to become more radical in its foreign economic relations, but its protectionism will not solve the fundamental problems it faces. China and Europe still need to further strengthen risk control and management in their economic and trade relations.展开更多

From the end of the Civil War to the eve of World War I, the United States blazed a new trail of industrial development and implemented protective policies such as high tariffs. This historical tradition has had a profound influence on some current US politicians. After the collapse of the Bretton Woods system, the United States developed a new form of mercantilism, as manifested in the emergence of nontariff barriers instead of tariff barriers to restrict imports and protect domestic industries and employment. Although export regulations have avoided affecting the technology industry, they have led to hefty trade deficits for the United States. National interests have prevailed in U.S. decision-making and have influenced its choices to accede to or walk away from international organizations or treaties. The dollar's hegemony has played a pivotal role in U.S. economic policymaking. These factors have led to the twin deficits in the U.S. economy, i.e. a trade deficit and a fiscal deficit. The real intention of the United States in waging a trade war against China is to maintain and even strengthen the dollar's hegemony and the U.S.' international predominance.展开更多

After reviewing Samuelson's and Kindleberger's trade theories, this paper finds that both Samuelson and Kindleberger are actually proponents of free trade, and that their common concern is falling US competitiveness due to its economic model, domestic institutional rules, and unilateralism. Both the "Samuelson's Concern" and "Kindleberger Trap" are distortions of Samuelson's and Kindleberger's original theories and the arguments' defense of protectionism cannot overcome the challenges confronting the U.S. and will destabilize international economic order.展开更多
