The United States has imposed multiple sanctions on Chinese companies for assisting the Russian military-industrial complex in its war against Ukraine. The US Department of Commerce and the Treasury alleged that several Chinese companies evaded US sanctions by selling sensitive technology needed by Russia to manufacture military weapons. One of these Chinese companies subject to US sanctions and its military dealings with Russia is “Sino Electronics Chinese Company,” which is considered as a part of a network of companies that has allegedly sent shipments worth approximately $200 million to Russia since the Chinese company was placed on the US sanctions list in September 2022. The shipments sent by the “Chinese Sino Network” to Russia included several microchips, cameras, and navigation equipment, technologies critical to Russian weapons used in its war with Ukraine, according to US accusations against Beijing.
These measures include broad US sanctions in 2024 and 2025 targeting entities in China and several other countries that support Russia’s war efforts. In October 2024, the US Treasury Department imposed sanctions on two Chinese drone companies, accusing them of participating in the production and supply of long-range attack drones to the Russian Air Force. Immediately following, in May 2024, US sanctions targeted Chinese companies and companies in several other countries for allegedly supplying electronic components and chemicals used in the manufacture of Russian weapons and missiles. US Treasury Secretary Janet Yellen also warned that “the United States will take action against any Chinese companies that assist Russia in its efforts to obtain military supplies.” As a result of these US sanctions, Chinese banks have become more cautious in dealing with Russia, leading to a slowdown in trade between the two countries during 2024.
Since July 2025, the United States has threatened to impose secondary sanctions on any entity that continues to cooperate with Russia in an attempt to isolate Moscow by striking its cross-border trade networks, particularly with China. Secondary sanctions target third parties that deal with the directly sanctioned country, Russia in particular. The sanctions are not imposed because of the actions of the third party, but rather because of its economic ties to the sanctioned entity. Washington uses these sanctions to deter any entity that might indirectly contribute to supporting the sanctioned regime or helping it circumvent sanctions. In 2018, the United States imposed sanctions on a Chinese bank for allegedly conducting financial transactions with North Korea, even though the bank itself had not previously been subject to any sanctions.
A series of US sanctions on China have been imposed, alleging its military cooperation with Russia in its war against Ukraine. In July 2025, US intelligence reports alleged that Chinese companies were shipping engines to the Russian arms company IEMZ Kupol by mislabeling them to evade sanctions.
The US Department of Commerce expanded its blacklist of Chinese companies and state-owned entities, alleging their cooperation with Russia and supporting it in its war against Ukraine. The US Department of Commerce added several Chinese companies to the US blacklist, including Shanghai Fudan Microelectronics, which was added to the US list of banned Chinese companies for supplying technology to the Russian military sector. Washington also imposed controls on the Chinese export sector, expanding export control restrictions to include Chinese companies that are 50% or more state-owned, as well as entities on the US blacklist.
Here, China has rejected all US accusations regarding its dealings with Russian military companies in its war against Ukraine. Beijing has repeatedly denied US accusations of providing military support to Russia. China has also taken several countermeasures, such as imposing sanctions on US companies, in a move to escalate trade tensions between the two countries. Regarding China’s response to US sanctions, China has publicly rejected all these accusations. At the same time, these US sanctions have raised concerns among Chinese banks and companies about secondary sanctions, which may indicate that these US measures are having an impact on trade relations between China and Russia.
As for China’s official response to the US sanctions imposed on it for its dealings with Russia, the Chinese Foreign Ministry confirmed in an official statement that the United States, by demanding that countries stop purchasing Russian oil, is participating in threatening and undermining international trade. In response to Trump’s threats regarding the purchase of Russian oil, the Chinese Foreign Ministry said in a statement that “China will take decisive countermeasures if its legitimate rights and interests are harmed, and that China opposes the United States using Beijing as a pretext to impose illegal unilateral sanctions on the Russian side.” The Chinese Foreign Ministry also stressed that “China has lodged a protest with Britain regarding the inclusion of Chinese companies on the sanctions list against Russia. Cooperation between Russian and Chinese companies should not be subject to interference or influence.” The Chinese Foreign Ministry also commented on the British sanctions imposed on it for allegedly dealing with Russian companies and entities, saying that “Beijing will take necessary measures to safeguard its legitimate rights and interests.”
China has categorically rejected all unilateral US sanctions against it, and the punitive tariffs imposed by Trump have angered Beijing. However, unlike Europe or other countries, China has shown confidence, with official Chinese authorities declaring that “it will fight to the end.” An official statement issued by China on October 13, 2025, stated that “threatening to impose high tariffs is not the right way to negotiate with China. The United States must adjust its position.” Beijing has already responded by imposing counter-tariffs and restrictions on US exports, including rare earths.
As for the nature of the sanctions directed against Russia in 2025, these new US sanctions focus on indirectly strangling the Russian economy by pressuring countries and companies that deal with Moscow in strategic sectors such as energy, metals, and technology. In July 2025, US President Donald Trump announced a 50-day deadline for reaching a peace agreement between Russia and Ukraine; otherwise, tariffs of up to 100% would be imposed on countries importing Russian oil or gas. Meanwhile, the US Congress is discussing a bill that would impose tariffs of up to 500% on Russian exports, including secondary sanctions on financing or transporting entities. Trump warned that all companies dealing with Russia, especially Chinese companies, entities, and institutions, particularly those operating in the technology and metals sectors, could be barred from entering the US market or using the international financial system.
Finally, regarding the impact of these unilateral US sanctions on China and other countries for allegedly dealing with Russian companies, I believe these US threats will not go unchallenged, as they could undermine confidence in the global economic system and raise questions about who has the right to punish whom and under what international legitimacy? Applying this to Russia, we find that Moscow is linked to extensive trade networks with major economies in strategic sectors such as energy, minerals, and food. These Russian entanglements with global economies make attempts to isolate Moscow a test not only of Washington’s ability but also of the ability of the entire global system to bear the cost of confrontation.
