One global perspective on world trade views exports and imports as complementary economic flows. Explain this concept.

A country's imports affect its exports and exports affect its imports. Every nation's imports arise from the exports of other nations. As the exports of one country increase, its national output and income rise, which in turn leads to an increase in the demand for imports. This nation's greater demand for imports stimulates the exports of other countries. Increased demand for exports of other nations energizes their economic activity, resulting in higher national income, which stimulates their demand for imports. In short, imports affect exports and vice versa.
