How does foreign trade lead to integration of markets across countries?

Solution:

Foreign trade leads to integration of markets across countries by the processes of imports and exports. Producers can make available their goods in markets beyond domestic ones via exports. Likewise, buyers have more choice on account of imports from other countries. This is how markets are integrated through foreign trade. For example, Japanese electronic items are imported to India, and have proved to be a tough competition for less-technologically-advanced companies here.
