Europe bases its economy on different economic activities. Though some of these activities are similar throughout the continent, Western Europe and Eastern Europe tend to have different focus areas. Western Europe bases much of its economic activities on service industries such as banking, trade, finance, and technology. Western Europe also manufactures products such as pharmaceuticals, automobiles, and aerospace crafts and technologies. Eastern Europe tends to focus on consumer goods and food processing.

The Cold War competition among the U.S and the Soviet Union continued for decades and ended in anti-communist mistrusts.
