International trade, the exchange of capital, goods, and services across borders, has shaped economies for centuries, from ancient trade routes like the Silk Road to modern globalization. It stimulates national GDP and promotes interdependence through intricate relationships involving currency, policy, and markets. Authors such as Hartley Withers emphasized its mutual benefits, framing it as a "handmaid" to economic cooperation, while Frank A.
Fetter highlighted the balance between imports and exports as a fundamental principle of trade theory. J. A. Hobson critiqued its competitive nature, comparing it to a "struggle" for market share, and Ronald Reagan associated it with national security, promoting policies to enhance trade ties. These viewpoints, ranging from economic theory to political strategy, illustrate trade as both a driver of growth and a field of negotiation, influenced by historical development and institutional structures like the WTO.
