Economic Coercion

When China blocked Australian coal imports in late 2020 — leaving dozens of vessels stranded offshore for months, their cargoes unsellable — it was not a routine trade dispute. It was a message: seek a COVID-19 origins inquiry, and your economy will pay. The episode distilled something that had been building for decades: the transformation of economic interdependence from a liberal peace dividend into a geopolitical weapon. Economic coercion now sits at the center of great-power competition, wielded by Washington and Beijing alike, reshaping alliance relationships, supply chains, and the rules of the international order.

Defining Economic Coercion¶

Economic coercion is the deliberate use of economic instruments — trade restrictions, financial sanctions, investment bans, debt leverage, regulatory pressure, or threats to market access — to compel a target state or non-state actor to change its political behavior. The key word is compel: coercion aims not merely to punish but to extract a specific policy concession. This distinguishes it from retaliatory trade measures taken in response to unfair commercial practices, though the line is often strategically blurred.

The instruments span a wide spectrum. At one end sit blunt tools: total trade embargoes, exclusion from financial messaging systems, asset freezes. At the other end are subtler instruments: quiet denial of market access, regulatory harassment of foreign firms, mobilization of consumer boycotts through state-controlled media. Between these poles lies a dense toolkit — export controls on critical technologies, investment screening regimes, secondary sanctions targeting third parties, debt traps that convert financial dependency into political leverage.

Geoeconomics — the use of economic statecraft to advance geopolitical objectives — is the broader framework within which economic coercion operates. Not all geoeconomic policy is coercive: foreign aid, trade agreements, and development finance can build influence without threatening punishment. But coercion is geoeconomics’ sharpest instrument, and its increasing use reflects a structural shift in how states compete.

Historical Antecedents¶

Economic coercion is not a modern invention. The British Royal Navy’s blockades during the Napoleonic Wars were exercises in systemic economic coercion — the Continental System and its countermeasures strangled European commerce for years, reshaping alliances and ultimately contributing to Napoleon’s decision to invade Russia. Great power competition has always had an economic dimension; what changes are the instruments and their reach.

The interwar experiment with collective economic sanctions under the League of Nations provided the modern era’s foundational lesson in coercion’s limits. When Italy invaded Abyssinia in 1935, the League imposed sanctions — but exempted oil, the commodity Mussolini most needed, because Britain and France feared escalation. The episode demonstrated a recurring problem: economic coercion is only as strong as the political will behind it, and that will tends to fracture under pressure from commercial interests and allied defection.

The Cold War produced two parallel economic blocs, each using economic instruments to discipline members and pressure adversaries. COCOM (Coordinating Committee for Multilateral Export Controls) restricted technology flows to the Soviet bloc; the US embargo on Cuba, dating to 1962, remains history’s longest-running unilateral coercive measure. The Soviet Union used energy dependence to constrain Eastern European states and, later, to project influence into Western Europe through Siberian natural gas pipelines — a dynamic whose implications would not become fully apparent until Russia’s 2022 invasion of Ukraine.

The American Coercion Toolkit¶

The United States has constructed the world’s most sophisticated economic coercion infrastructure, built on the dollar’s centrality to global finance. The architecture has several interlocking components.

SWIFT exclusion — denial of access to the Society for Worldwide Interbank Financial Telecommunication messaging system — became a headline instrument after its application to Iran in 2012 and Russia in 2022. Because most international financial transactions are denominated in dollars and cleared through US correspondent banks, exclusion from SWIFT effectively cuts a country off from the global financial system. The measure against Russia in 2022 was the most significant financial weapon deployed against a major economy in history, though its incomplete application (some Russian banks were exempted to allow energy payments) revealed the same political compromises that plagued League of Nations sanctions.

Export controls have re-emerged as a primary tool under the CHIPS and Science Act logic: deny adversaries access to advanced semiconductors and the equipment to manufacture them. The October 2022 semiconductor controls against China were arguably the most aggressive technology export restrictions since COCOM, targeting not just American firms but any company worldwide that uses American equipment in its fabrication process — a form of extraterritorial jurisdiction that asserted US control over global supply chains.

Secondary sanctions — penalties imposed on third parties that do business with a sanctioned country — extend US coercive reach far beyond its own economy. They work because access to the US market and dollar clearing is so valuable that most firms and banks comply, even if their home governments object. The European Union has formally protested secondary sanctions on multiple occasions, yet European companies have largely complied with US Iran and Russia sanctions rather than risk exclusion from American markets.

CFIUS (Committee on Foreign Investment in the United States) investment screening has expanded significantly since 2018, blocking Chinese acquisitions of sensitive technology companies. The instrument works in reverse too: restricting US investment in Chinese advanced technology sectors, as ordered in 2023, limits capital and knowledge flows that Beijing needs for technological advancement.

Chinese Economic Coercion: A Pattern of Cases¶

China has deployed economic coercion with increasing frequency and sophistication, though its effectiveness has been uneven. Several cases define the pattern.

The Australia episode (2020-2023) is the most studied. After the Morrison government called for an independent investigation into COVID-19’s origins, Beijing imposed restrictions on Australian barley, wine, beef, coal, copper, cotton, and timber — products worth roughly AUD 20 billion annually. The measures were officially framed as trade compliance issues; the timing made the political motivation transparent. The campaign ultimately failed: Australia found alternative markets for most affected goods, the economic damage was absorbed, and Canberra did not withdraw its inquiry demand. When Australia-China relations eventually normalized in 2023, it was on Australia’s terms. The coercion had hardened domestic opinion rather than producing compliance.

The Lithuania case (2021-2022) carried higher stakes for the architecture of international trade. After Vilnius permitted Taiwan to open a representative office under the name “Taiwan” (rather than the usual diplomatic fiction of “Taipei”), China blocked Lithuanian goods from entering Chinese territory and — crucially — threatened to block goods from other EU member states if they contained Lithuanian inputs. This attempt to leverage China’s position in European supply chains directly targeted the EU’s single market integrity. The European Commission invoked its newly designed Anti-Coercion Instrument framework in response, and Lithuania ultimately received increased US and EU political support. The episode accelerated European discussions about de-risking supply chains from China.

South Korea’s THAAD experience (2016-2017) demonstrated China’s willingness to impose costs on security decisions within the US alliance framework. When Seoul agreed to deploy the Terminal High Altitude Area Defense missile system following North Korean provocations, Beijing orchestrated what it officially denied: tourism boycotts, pressure on Chinese consumers to avoid Korean brands (particularly Lotte, which provided land for the THAAD site), restrictions on Korean entertainment content, and informal limits on Korean cultural exports. The economic damage was real, and the episode left a lasting mark on South Korean strategic calculations about the costs of security cooperation with the United States.

Norway learned a similar lesson earlier. After the Nobel Committee — an independent body over which Oslo has no authority — awarded the 2010 Peace Prize to imprisoned Chinese dissident Liu Xiaobo, China banned Norwegian salmon imports and blocked other bilateral exchanges. Norwegian diplomats spent years in cold-shoulder treatment before relations normalized in 2016. The episode illustrated the expansive conception of “interference in internal affairs” that Beijing applies: even acts by formally independent institutions trigger state-level retaliation.

Weaponized Interdependence¶

The theoretical framework that best explains how economic coercion works in the contemporary era was articulated by political scientists Henry Farrell and Abraham Newman in their 2019 paper “Weaponized Interdependence.” Their argument is structural: global economic networks are not flat. They have hubs — nodes through which disproportionate flows of goods, finance, or data pass. States that control these hubs can use network position to gather intelligence (panopticon effect) or to cut off rivals (chokepoint effect).

The dollar clearing system is the paradigmatic financial hub: almost all significant international transactions pass through US correspondent banks, giving Washington visibility into and leverage over global financial flows. The semiconductor supply chain has a different topology, but a similar hub structure: advanced chip fabrication depends on extreme ultraviolet lithography machines produced almost exclusively by the Dutch firm ASML, whose production in turn depends on components and software from hundreds of US suppliers. This creates a chokepoint through which export controls can constrain Chinese technological development.

De-dollarization efforts by Russia, China, and others are fundamentally attempts to reduce exposure to these hubs — to escape the panopticon and the chokepoint by building alternative networks. Progress has been real but slow: the dollar’s share of global reserves has declined from roughly 73% in 2001 to around 57% in 2024, but no viable alternative clearing system yet challenges SWIFT’s dominance for most transactions.

The Limits of Economic Coercion¶

Decades of empirical research have produced a sobering verdict on economic coercion’s effectiveness. The foundational study by Gary Hufbauer, Jeffrey Schott, and Kimberly Ann Elliott, examining hundreds of sanctions episodes since World War I, found success rates below 30% for major policy objectives. More recent scholarship, controlling for selection bias (coercive measures are more likely to be attempted when they are expected to work), finds even lower rates.

Several structural factors limit effectiveness. Target states can absorb costs if the demanded concession conflicts with vital interests or regime survival — North Korea and Iran have sustained sanctions regimes for decades rather than abandon nuclear programs. Third-party substitution undermines coercion: when China blocked Australian coal, India, Japan, and European buyers increased purchases; when Western sanctions targeted Russian oil, India and China absorbed the flows. The global economy’s size and complexity creates alternative pathways that undermine exclusion.

Coercive measures also tend to harden political sentiment in target states, creating nationalist rallying effects that make compliance more politically costly for target governments. The population absorbs economic pain partly as a badge of national resistance, and leaders who capitulate to foreign economic pressure face domestic legitimacy costs. Iran’s nuclear program survived decades of sanctions. Cuba’s government survived six decades of American embargo. Russia’s economy, though severely damaged by 2022 sanctions, continued functioning through redirected trade flows.

Counter-Coercion Architecture¶

The recognition that economic coercion has become a systemic feature of the international environment has driven efforts to build defensive and retaliatory capacity. The European Union’s Anti-Coercion Instrument (ACI), adopted in late 2023, is the most significant institutional response. It empowers the EU to impose countermeasures — trade restrictions, investment barriers, intellectual property restrictions — against any third country that uses economic coercion against an EU member or the single market as a whole. The China-Lithuania episode was its direct inspiration.

The US CHIPS and Science Act (2022) and Inflation Reduction Act (2022) represent a different form of counter-coercion: reducing vulnerability by rebuilding domestic capacity in critical sectors. The explicit goal is to reduce dependence on Chinese-controlled supply chains in semiconductors, batteries, and rare earths — thereby limiting Beijing’s coercive leverage over US technology sectors. The semiconductor chokepoint runs in both directions: China controls roughly 60-80% of global rare earth processing, and future coercion scenarios involving rare earth export restrictions (previewed by restrictions on gallium and germanium in 2023) represent a significant vulnerability in Western defense and technology supply chains.

Future Vectors: AI, Data, and Rare Earths¶

The frontier of economic coercion is moving toward domains where network topology is still being established. Artificial intelligence development depends critically on training data, computing infrastructure, and algorithmic talent. States that can control access to high-quality training datasets, cloud infrastructure, or specialized AI chips gain coercive leverage over AI-dependent industries worldwide.

Data localization requirements — mandating that data about citizens or transactions be stored within national borders — are both economic instruments and potential coercive tools. States with large domestic markets (China, the EU, increasingly India) can use data localization to force technology companies to maintain separate infrastructure and comply with local regulatory demands, effectively holding market access hostage to political compliance.

Rare earth dependencies represent perhaps the most straightforward future coercion vector. China controls processing of roughly 85% of global rare earth elements essential to electric vehicles, wind turbines, advanced electronics, and military guidance systems. The 2010 episode when China restricted rare earth exports to Japan during a territorial dispute previewed the leverage available; 2023 restrictions on gallium and germanium exports confirmed Beijing’s willingness to use this tool. Western efforts to develop alternative processing capacity are underway but will take years to mature.

Sanctions and economic coercion will continue to evolve as technologies and trade patterns shift. The key question is whether the weaponization of interdependence ultimately destroys the interdependence itself — fracturing the global economy into rival blocs — or whether the costs of fragmentation are high enough to create new norms and institutions limiting coercive use. The answer will shape the architecture of the international economy for decades.
