Economic relations between Russia and China remain high. Beijing has become Moscow's most important trading partner, and in the context of Western sanctions, it has also become an alternative source of industrial and consumer goods, as well as the largest market for Russian energy and other raw materials. At the same time, external political factors may have a growing influence on Russian-Chinese economic relations. These include the trade war between China and the United States, a possible escalation of US sanctions against Russia, and the expansion of secondary sanctions by the European Union against Chinese companies.

The trade war, in the form of increased import duties on imported goods, has become one of the calling cards of Donald Trump's second term in office. The executive order he issued on April 2, 2025, provided a detailed conceptual justification for such a policy. The main goal is the reindustrialisation of the United States through the return or transfer of industrial production to the territory of the US, as well as an equalization of the trade balance with foreign countries. The basic part of Trump's order concerned all countries throughout the world and assumes a tariff increase of 10%. It goes on to determine individual duties on the goods of more than 70 countries, with its own sets for each.

China became one of the few countries which decided to mirror the tariff increases. This led to a short-lived and explosive exchange of increases in duties. While it was suspended by negotiations between the two countries in Geneva, it was not removed from the agenda. In the US trade war “against the whole world”, China remains a key target. This is determined by the high level of the US trade deficit in relations with China, which has persisted for more than 40 years. Apparently, it remained comfortable for the US until China made a noticeable leap in the field of industrial and technological development. Such a leap allowed China to gradually overcome its peripheral place in the global economy, displace American and other foreign goods from the domestic market, and occupy niches in foreign markets. Despite the critically important role of American components, patents and technological solutions in a number of industries, China has managed to reduce its dependence on them. The growing industrial and technological power of the PRC is becoming a a political problem for the US. It was clearly identified during the first term of Trump's presidency. Even then, the US pursued a course toward the technological containment of China.

Despite the temporary respite in the trade war, US pressure on China will remain. The tariff policy may be supplemented by restrictive new measures (sanctions) in the field of telecommunications and other industries. During the new term of Donald Trump's presidency, the politicisation of issues that the Biden administration avoided putting at the forefront of US-Chinese relations began again. These include the problem of Hong Kong autonomy and the issue of ethnic minorities in the Xinjiang Uyghur Autonomous Region of China. Both issues received a high level of politicisation during Trump's first term.

The US-China trade war has so far had little effect on Russian-Chinese relations. The increase in US tariffs has had virtually no effect on Russia. Russia is already facing a significant number of restrictive measures, and the volume of trade with the United States has been reduced to near zero since the start of Moscow’s Special Military Operation in 2022. However, Russia may feel the effects of the trade war. For example, the United States may require China to purchase American energy resources as a measure to correct the trade balance. Obviously, such a measure is unlikely to solve the imbalance. However, it has the potential to affect the volume of Russian oil supplies to China in one way or another. In addition, the trade war as a whole may affect oil prices downwards, which is also disadvantageous for Russia. On the other hand, Russia is a reliable supplier of energy resources for China, which will not politicise them. Even in the context of new aggravations of the trade war, China is unlikely to refuse Russian supplies.

Another factor is US sanctions against Russia. After the start of Russian-American negotiations on Ukraine in 2025, Washington avoided using new sanctions, although all previously adopted restrictive measures and their legal mechanisms are in force. However, Donald Trump failed to carry out a diplomatic blitzkrieg and achieve a quick settlement. The negotiations have dragged on and may continue for a long time. If they fail, the United States is ready to escalate sanctions again. Existing legal mechanisms allow, for example, for an increase in the list of blocked persons, including in relation to Chinese companies cooperating with Russia. This practice was widely used by the Biden administration. It was Chinese companies that became the key target of US secondary sanctions targeting Russia. They fell under blocking financial sanctions for deliveries of industrial goods, electronics and other equipment to Russia. However, there was not a single large company among them. We were talking about small manufacturing companies or intermediary firms. At the same time, the Biden administration managed to significantly complicate payments between Russia and China through the threat of secondary sanctions. US Presidential Executive Order 14114 of December 22, 2023 threatened blocking sanctions against foreign financial institutions carrying out transactions in favour of the Russian military-industrial complex. In practice, such sanctions against Chinese financial institutions were practically not applied, except for the blocking of several Chinese payment agents in January 2025. However, the very threat of secondary sanctions forced Chinese banks to exercise a high level of caution in transactions with Russia. This problem has not yet been fully resolved.

New legal mechanisms in the field of sanctions, which are being worked on in the United States, may also affect Russian-Chinese relations. We are talking about the bill introduced by US Senator Lindsey Graham and several other senators and members of congress. Their bill assumes that in the event of failure of negotiations with Russia on Ukraine, the US executive branch will receive the authority to impose 500% duties on countries purchasing Russian raw materials, including oil. China may be among them. This threat should hardly be exaggerated for now. The passage of the bill is not predetermined. Even if it is signed into law, the application of 500% tariffs against China will be an extremely difficult matter. Recent rounds of the trade war have shown that China is ready for retaliatory measures. However, the emergence of such a norm will in any case increase the risks for business and may negatively affect Russian suppliers of raw materials.

Another factor is EU sanctions policy. Unlike the US, the EU continues to escalate sanctions against Russia despite the negotiations on Ukraine. Brussels is expanding the practice of secondary sanctions, which also affect Chinese companies. In the context of a deepening economic partnership between China and the EU, this factor seems significant. However, in reality, it will play a peripheral role. The EU's practice of secondary sanctions is still significantly more limited than the American one. It does not affect any significant Chinese companies. Problems may be created by the expansion of EU bans on the provision of financial messaging services for Russian banks—this will affect their relations with Chinese counterparties. But such bans stimulate the acceleration of the use of the Chinese CIPS payment system by Russians, which has the functionality of transmitting financial messages. Compared to the US, the EU policy factor remains secondary.
