Investment and trade between the U.S. and the European Union (EU) have expanded exponentially since Europe first began to integrate its market in the 1950s. Currently the U.S. and EU account for more than one trillion dollars in two-way trade and investment flows, directly supporting a total of more than six million jobs in the U.S. and the 15 EU countries and resulting in a degree of economic integration higher than that between the U.S. and Asia. The EU and U.S. now exchange roughly 19% of each other's exports and imports.
