The European Union and the United States have the largest bilateral trade and investment relationship and enjoy the most integrated economic relationship in the world.

EU and US investments are the real driver of the transatlantic relationship, contributing to growth and jobs on both sides of the Atlantic. It is estimated that a third of the trade across the Atlantic actually consists of intra-company transfers.
The transatlantic relationship also defines the shape of the global economy as a whole. Either the EU or the US is the largest trade and investment partner for almost all other countries in the global economy.
