List of countries by leading trade partners

For most economies worldwide, their leading export and import trading partners in terms of value are typically the United States, the European Union (EU) or China. Emerging markets such as Russia, Brazil, India, South Africa, Saudi Arabia, the UAE, Turkey, and Iran are becoming increasingly important as major markets or source countries in various regions.

For individual EU member states, intra-EU trade is collectively greater than trade with any other partner. Both the EU and the United States have China as their largest source of imports. Conversely, the EU is China's largest source of imports. While the EU and the United States dominate as the largest trading partners in many parts of the world, other countries such as Brazil, Russia, and South Africa are gaining prominence within their respective regions.^{[citation needed]}

Some countries, especially isolated ones, heavily rely on a larger neighbouring country for trade. For instance, Venezuela is a key export market for Cuba, while Uzbekistan, being doubly-landlocked, primarily exports to its singly-landlocked neighbours, Tajikistan and Afghanistan.
