The Weaponization of Trade: Economic Sanctions as a Tool of Modern Diplomacy

Abstract

In the contemporary international order, trade has evolved from a vehicle of interdependence and cooperation into an instrument of strategic coercion. The increasing reliance on economic sanctions as tools of modern diplomacy reflects a broader shift in global power politics — from military confrontation to economic statecraft. This paper examines the weaponization of trade through the lens of economic sanctions, analyzing their effectiveness, ethical dimensions, and geopolitical consequences. Drawing upon theories of economic statecraft, realism, and liberal institutionalism, the research explores how states use sanctions to project influence and enforce compliance without direct military engagement. It investigates key case studies, including U.S. sanctions on Iran, Western sanctions on Russia following the Ukraine conflict, and the U.S.–China trade and technology war. The findings suggest that while sanctions have become the preferred diplomatic instrument for major powers, they often yield mixed outcomes, producing humanitarian crises, market disruptions, and global economic fragmentation. This study argues that sanctions, as a form of weaponized trade, blur the boundary between economic cooperation and coercion, reshaping the international system into one characterized by selective interdependence, strategic rivalry, and contested norms of legitimacy. The paper concludes by recommending more ethical, multilateral, and transparent sanction mechanisms to ensure diplomacy remains a tool for peace rather than economic domination.
