The agreement of U.S. President Donald Trump and Chinese President Xi Jingping to restart trade talks put offs planned increases of tariffs on Chinese exports. But there is little doubt that the U.S. intends to move ahead with its intention to undo the economic integration that has been underway since the 1990s. Even when it proves impossible to reverse history, the consequences of such a move will have long-lasting consequences for the global economy.
To understand what is at stake, think of the following simple guide to the status of the world’s nations in the aftermath of World War II. Countries separated into three groups, each anchored on its own tectonic plate. The “first world” consisted of the advanced economies of the U.S., Canada, the West European nations, Japan, Australia and New Zealand. These economies enjoyed rapid growth in the 1950s and 1960s, due in part to the expansion of trade amongst them. The formation of the European Community (now Union) eventually led to a single market in goods and services, capital and labor for its members. The largest of the advanced economies exerted their control through the “Group of Seven,” i.e., France, Germany, Italy, Japan, the United Kingdom and the U.S. Their leaders met periodically to discuss economic and other types of policies and issued communiques that listed their agreements. Their predominance extended to their control of the International Monetary Fund and the World Bank.
The “second world” included the Communist nations: the Soviet Union and the countries it controlled in Eastern Europe, as well as China and North Korea. These were command economies, run by government ministers. There was some commerce between the Soviet Union and its East European satellites, but all trade was managed. There were virtually no commercial or financial interactions with the first world.
