{{Short description|Chinese fleet involved in illegal activities}} Ships from the People's Republic of China or those operated by Chinese nationals sometimes use methods to evade economic sanctions in order to fish illegally or import oil from Iran, operating as a shadow fleet.

== Background == China's dark fleet expanded during the 2000s, first to increase amounts of seafood fishing and later for obtaining oil from countries like Iran and Venezuela.<ref name="bloomberg">{{Cite news |title=The Clandestine Oil Shipping Hub Funneling Iranian Crude to China |url=https://www.bloomberg.com/graphics/2024-iran-south-china-sea-oil-trade/ |archive-url=https://web.archive.org/web/20250728193220/https://www.bloomberg.com/graphics/2024-iran-south-china-sea-oil-trade/ |archive-date=2025-07-28 |access-date=2025-08-10 |work=Bloomberg.com |language=en}}</ref><ref>{{Cite web |title=Venezuela and Iran Use 'Dark Fleet' to Evade Oil Sanctions |url=https://www.thetrumpet.com/27742-venezuela-and-iran-use-dark-fleet-to-evade-oil-sanctions |access-date=2025-08-10 |website=theTrumpet.com |language=en |archive-date=2023-06-18 |archive-url=https://web.archive.org/web/20230618165822/https://www.thetrumpet.com/27742-venezuela-and-iran-use-dark-fleet-to-evade-oil-sanctions |url-status=live }}</ref> Chinese and Taiwanese fishing fleets are the world's largest, followed by those of Japan, South Korea, and Spain.<ref>{{Cite news |title=Battle to stop Africa’s waters being ravaged by China’s d... |url=https://observer.co.uk/news/oceans/article/battle-to-stop-africas-waters-being-ravaged-by-chinas-dark-fishing-fleets |access-date=2025-10-15 |newspaper=The Observer |language=en |archive-date=2025-12-08 |archive-url=https://web.archive.org/web/20251208174330/https://observer.co.uk/news/oceans/article/battle-to-stop-africas-waters-being-ravaged-by-chinas-dark-fishing-fleets |url-status=live }}</ref>

== Methods == Ships of Chinese origin employ several means to evade detection.

== Locations == Fleets from China have fished illegally off the coasts of Ecuador and Peru near the Galápagos Islands, into the Argentine Sea of Argentina, along the shores of West Africa, as well as in North Korean waters, creating impacts that are felt among coastal communities of South Korea and Russia.<ref name="he360" /><ref name="newsweek" /><ref>{{Cite news |last=McCurry |first=Justin |date=2020-07-22 |title=North Korea's 'ghost ships' linked to illegal fishing by China fleet, study finds |url=https://www.theguardian.com/world/2020/jul/22/hundreds-of-chinese-boats-fishing-illegally-off-north-korea-study-finds |access-date=2025-09-07 |work=The Guardian |language=en-GB |issn=0261-3077}}</ref><ref>{{Cite web |date=2023-03-23 |title=Illuminating dark fishing in North Korea |url=https://globalfishingwatch.org/success-story/illuminating-dark-fishing-in-north-korea/ |access-date=2025-09-07 |website=Global Fishing Watch |language=en-US |archive-date=2025-09-09 |archive-url=https://web.archive.org/web/20250909045254/https://globalfishingwatch.org/success-story/illuminating-dark-fishing-in-north-korea/ |url-status=live }}</ref> Transfers of crude oil from Iran to China have taken place in the waters off Malaysia; neither China nor Malaysia are legally bound by United States sanctions against Iran.<ref name="bloomberg" /><ref name="lloydslist" />

== Implications ==

=== Economic === Most of the vessels in the Chinese shadow fleet operate without the overt oversight of large entities. Some of them are more than a decade old and can be difficult to detect when their AIS transponders are off. This increases the risk of a collision or oil spill. In the past when other dark fleet vessels had accidents, their owners were difficult to identify and track down.<ref name="bloomberg" />

=== Geopolitical === China's dark fleet is used by Beijing to maintain independence in areas like energy and food supply.<ref>{{Cite web |date=2025-08-04 |title=China's 'Dark Fleet' working to evade sanctions, import Iranian oil |url=https://www.intellinews.com/china-s-dark-fleet-working-to-evade-sanctions-import-iranian-oil-394350/ |access-date=2025-08-10 |website=www.intellinews.com |language=en |archive-date=2025-08-04 |archive-url=https://web.archive.org/web/20250804053926/https://www.intellinews.com/china-s-dark-fleet-working-to-evade-sanctions-import-iranian-oil-394350/ |url-status=live }}</ref><ref name="yahoo">{{Cite web |date=2025-08-01 |title=How China uses 'dark fleets' to circumvent trade sanctions |url=https://www.yahoo.com/news/articles/china-uses-dark-fleets-circumvent-194457878.html |access-date=2025-08-10 |website=Yahoo News |language=en-US |archive-date=2026-02-15 |archive-url=https://ghostarchive.org/archive/iz0Ic?wr=false |url-status=live }}</ref> It is a powerful tool for the country's strategy in sensitive areas such as the South China Sea, East China Sea, and Yellow Sea, where they can collect intelligence, monitor foreign activity, and strengthen China's territorial claims in disputed water.<ref>{{Cite web |title=China continues to prioritize maintaining, expanding global port presence for its distant-water fleet |url=https://www.seafoodsource.com/news/supply-trade/china-continues-to-prioritize-maintaining-expanding-global-port-presence-for-its-distant-water-fleet |access-date=2025-08-10 |website=www.seafoodsource.com |language=en |archive-date=2025-08-25 |archive-url=https://web.archive.org/web/20250825104409/https://www.seafoodsource.com/news/supply-trade/china-continues-to-prioritize-maintaining-expanding-global-port-presence-for-its-distant-water-fleet |url-status=live }}</ref><ref>{{Cite web |last1=Spey |first1=Joseph Reilly |date=2025-08-04 |title=Shadow Fleets and Sea Denial |url=https://www.usni.org/magazines/proceedings/2025/august/shadow-fleets-and-sea-denial |access-date=2025-08-10 |website=U.S. Naval Institute |language=en |archive-date=2025-08-10 |archive-url=https://web.archive.org/web/20250810220352/https://www.usni.org/magazines/proceedings/2025/august/shadow-fleets-and-sea-denial |url-status=live }}</ref>

== Reactions ==

=== United States === In recent years the United States has issued new sanctions targeting more than 50 individuals, entities, and over 50 vessels linked to China's dark fleet and its clandestine oil transport networks, supporting Iran. The United States regards these actions as the most extensive since the 2018 "maximum pressure" campaign. Investigations that were conducted have monitored an rise in ship-to-ship oil transfers in international waters near Malaysia. In addition, the United States and other international officials documented unprecedented activity and revenue flows of up to $70&nbsp;billion, enabling Iran to sustain its regime and nuclear ambitions despite sanctions.<ref>{{Cite web |last=Team |first=Editorial |date=2025-08-01 |title=China helps the Iranian Islamic regime evade United States sanctions |url=https://derechadiario.com.ar/us/argentina/china-used-a-secret-fleet-to-conduct-secret-transactions-with-iranian-oil |access-date=2025-08-10 |website=La Derechadiario US |language=en |archive-date=2025-08-15 |archive-url=https://web.archive.org/web/20250815163008/https://derechadiario.com.ar/us/argentina/china-used-a-secret-fleet-to-conduct-secret-transactions-with-iranian-oil |url-status=live }}</ref><ref>{{Cite web |date=2025-08-04 |title=China's 'Dark Fleet' working to evade sanctions, import Iranian oil |url=https://www.ifmat.org/08/04/chinas-dark-fleet-working-to-evade-sanctions-import-iranian-oil/ |access-date=2025-08-10 |website=IFMAT |language=en-US |archive-date=2025-08-05 |archive-url=https://web.archive.org/web/20250805161236/https://www.ifmat.org/08/04/chinas-dark-fleet-working-to-evade-sanctions-import-iranian-oil/ |url-status=live }}</ref><ref>{{Cite web |date=2025-08-01 |title=How China uses 'dark fleets' to circumvent trade sanctions |url=https://theweek.com/world-news/dark-fleets-china-ocean |access-date=2025-08-10 |website=The Week |language=en |archive-date=2025-08-14 |archive-url=https://web.archive.org/web/20250814012709/https://theweek.com/world-news/dark-fleets-china-ocean |url-status=live }}</ref> The vessels ''Alps'' (alias), ''Eon'', and ''Stellar Oracle'' have been sanctioned for their involvement''.''<ref name="cbsnews">{{Cite web |date=2025-07-31 |title=China uses "dark fleet" to buy oil from Iran and evade U.S. sanctions in international waters - CBS News |url=https://www.cbsnews.com/news/china-iran-us-sanctions-dark-fleet/ |access-date=2025-08-10 |website=www.cbsnews.com |language=en-US |archive-date=2025-08-08 |archive-url=https://web.archive.org/web/20250808053628/https://www.cbsnews.com/news/china-iran-us-sanctions-dark-fleet/ |url-status=live }}</ref>

=== Other countries === In addition to the United States, United Kingdom and the European Union have tried to ban certain ships and limit the insurance and shipping services that support China's dark fleet. But as different countries have different standards, these efforts have encountered problems. Trying to target companies and insurers involved in these illegal actions has made it harder for global businesses to handle risks and follow maritime trade rules.<ref name="yahoo"/><ref>{{Cite web |last=Kypriotaki |first=Anastasia |date=2025-08-06 |title=Shadow fleet keeps expanding despite sanctions and regulations |url=https://safety4sea.com/shadow-fleet-keeps-expanding-despite-sanctions-and-regulations/ |access-date=2025-08-10 |website=SAFETY4SEA |language=en-US}}</ref>
