The capacity to convert interdependence into weight, and to withstand conversion attempted in return: the asymmetries of dependence, the coordination machinery that reads and responds to coercion, and the demonstrated ability to hold a position under economic pressure.
The Capability Development Index tracks the events that move a capability — operational use, technical breakthroughs, procurement decisions and the industrial base behind them — and places each on the record with the date it happened.
Recent developments cover the current period. Historical developments are the inflection points that produced Economic Leverage & Coercion Resistance as it stands today.
Control of Constantinople and the eastern Mediterranean let the Ottomans set the terms on which Asian spices and silk reached Europe, a chokehold that prompted Portugal and Spain to fund sea voyages seeking routes that bypassed Ottoman middlemen entirely.
Colonial trade was confined to English ships and routed through English ports, a deliberate use of market access rules to bind colonies into dependency and starve rival Dutch shipping of trade, a template for mercantilist trade coercion for two centuries.
Victory at the Battle of Plassey let the Company dictate textile and revenue terms across one of the world's richest trading regions, converting a commercial trading operation into an instrument of coercive economic and territorial control.
The decree barred European states allied with or occupied by France from trading with Britain, an attempt to use control of continental markets to strangle a rival's economy that instead fuelled smuggling and resentment across the blockaded territories.
Victory in the First Opium War produced the Treaty of Nanking, ceding Hong Kong and opening five ports to British trade on Britain's terms, a stark demonstration of trade access imposed through coercion rather than negotiation.
The Coordinating Committee for Multilateral Export Controls restricted the sale of technology and equipment with military applications to communist states, an early template for using collective control of trade access as an instrument of Cold War strategy.
Producers cut output and halted sales to states seen as supporting Israel in the October war, quadrupling world oil prices within months and demonstrating for the first time that control of a critical resource could be wielded as a coercive geopolitical weapon.
President Carter halted grain sales in response to the invasion of Afghanistan, seeking to use America's dominance of world grain exports as a foreign policy lever, though the embargo was widely judged to have hurt American farmers more than Soviet consumers.
Chinese think tanks developed a broader strategic framework known as the new security concept during the 1990s. It provided the doctrinal setting within which economic tools were later positioned as instruments of statecraft.
A pricing and transit dispute led Gazprom to halt deliveries through Ukraine for weeks in the depths of winter, disrupting supply to several European countries and illustrating how control of a pipeline network could be used as diplomatic leverage.
From the 2010s China changed its strategic doctrine and began using economic diplomacy more frequently as a means of coercion. This marked a decisive shift in how a major economy deployed trade access and resource control for political ends.
After the Norwegian Nobel Committee awarded the Peace Prize to dissident Liu Xiaobo, China suspended free trade agreement negotiations with Norway and imposed new veterinary inspections on Norwegian salmon. Salmon import volumes from Norway fell by 60% in 2011, illustrating targeted market-access coercion.
During a maritime dispute near the Senkaku or Diaoyu islands, China halted or quietly curtailed rare earth shipments to Japan, demonstrating Beijing's willingness to use its dominance of rare earth processing and this critical mineral supply chain as diplomatic pressure. The incident became a defining example of resource-based coercion, prompting Japan and others to fund alternative supply and recycling and raising wider concern about supply chain dependency.
China combined trade restrictions with naval deployment in a dispute with the Philippines. The episode showed economic coercion being paired with military signalling.
India created a dedicated development partnership body to administer aid and concessional finance abroad. The wing manages housing projects in Sri Lanka, a transmission line in Puli Khumri, Afghanistan, and Lines of Credit worldwide, particularly in Africa.
Fund lawyers argued that clear legal frameworks were needed to underpin governance as Gulf, Asian and other state-owned investment vehicles grow larger and take on wider mandates, funds increasingly used by their governments as instruments of economic diplomacy as much as pure return-seeking.
Rising defence spending was found to force difficult fiscal trade-offs even for countries not directly involved in fighting, with the Fund arguing that recovery for conflict-affected states depends on reducing uncertainty, rebuilding capital and helping displaced populations return, all of which reshape trade and investment patterns for years.
The Fund's growth forecasts were revised down and policy priorities reshaped around the conflict's fallout, with officials calling for stronger global cooperation to contain the damage, a reminder of how much weight a single regional conflict now carries in the world's collective economic calculus.
IMF officials found markets had stayed broadly orderly despite the conflict, but warned that continued fighting or a wider escalation could test financial stability further, underscoring how far a regional war could ripple through global capital markets well beyond the combatant states.
The Continental Critical Minerals Value Addition Framework set out a collective African position for negotiating with foreign buyers and processors, responding to years in which the continent held around 30% of critical mineral reserves but captured only about 10% of the value they generated.
State railway operator Kazakhstan Temir Zholy pushed to raise transit volumes on the Trans-Caspian route by 65% this year, giving China and Europe a path that bypasses Russian territory entirely and giving Kazakhstan and its neighbours new standing as gatekeepers of an alternative Eurasian trade route.
Jakarta raised nickel royalties and cut the 2026 ore-mining quota, terms that foreign smelters and battery makers must accept if they want continued access to the world's largest nickel reserves, using control of the raw material as leverage to steer investment toward domestic processing.
World Bank data showed developing-country exports to the United States fell $55 billion, or 8.6%, over seven months compared with a year earlier, while exports to other high-income countries rose 5.9% and to other developing economies rose 10.3%, evidence of a deliberate hedge against reliance on any single market's goodwill.
Attacks on vessels transiting the Bab-el-Mandeb strait forced ships away from the Suez Canal and around southern Africa, pushing Asia-Europe freight costs up roughly fivefold and demonstrating how a comparatively small force controlling a narrow strait could impose costs on trade far beyond the immediate conflict.
Chinese exports to ASEAN rose 13.4% and to Africa 25.8% even as growth in shipments to Western markets slowed, a reorientation that gave Beijing deeper commercial relationships and greater diplomatic goodwill across the developing world at a moment of rising trade tension with the US and Europe.
The inaugural dialogue took place in San Francisco and Silicon Valley from 10 to 13 June 2024. It extended economic statecraft into digital technology cooperation between the two states.
Negotiations towards a comprehensive economic partnership agreement began on 21 June 2021 and reached an eighth round in Ottawa in June 2024. Leaders of the two countries met on 5 September 2023 and set a target of concluding the talks before the end of 2024.
In a speech on 4 October 2018 Pence set out that the United States would pressure China to change its stance on discriminatory trade barriers, forced technology transfer and militarisation of South China Sea outposts. The address formalised trade leverage as an explicit instrument of American strategy.
From 2016 the United States executed a series of measures against China over discriminatory trade barriers, forced technology transfer and other disputes. Reported tariff plans would have affected over $200 billion of imports, including consumer goods and smart products.
