Current political and economic issues succinctly explained.

Putin Floats China as Security Guarantor for Ukraine: Ahead of the peace summit in Alaska between U.S. President Donald Trump and Russian President Vladimir Putin, Putin requested a phone call with Chinese President Xi Jinping. According to CCTV, the Chinese state television broadcaster, Xi expressed his support for renewed contact and improved relations between the United States and Russia to achieve a peaceful end to the Russia-Ukraine war. Xi also reiterated China’s desire for a diplomatic strategy, reportedly describing the war as a complex set of issues with no easy solutions. That call was the second between the two leaders in less than two months.

Chinese Foreign Ministry spokesperson Mao Ning echoed Xi’s comments when asked during a press conference on August 12 about the absence of Ukrainian representatives expected at the summit. Ning stated that “China supports all efforts that are conducive to the peaceful resolution of the crisis. . . . We expect that all parties and stakeholders can participate in the peace negotiation process in a timely manner and reach a fair, lasting, binding peace agreement that is acceptable to all parties as soon as possible.”

China has publicly maintained its support for a peaceful resolution since the war began and has positioned itself as a potential mediator in the conflict. Comments following the Alaska summit reflected the same sentiment. On August 19, Ning said that “dialogue and negotiation is the only viable way out of the Ukraine crisis.”

However, what, if any, role China will play in the peace process remains unclear. During the summit, Putin expressed his openness to discussing security guarantees for Ukraine and reportedly suggested that China could act as one such guarantor, according to unnamed sources who spoke to Axios. The idea of China serving that function in the region is not new. In an accord drafted by Russia and Ukraine in 2022, known as the Istanbul Protocol, Russia demanded to be considered a security guarantor of Ukraine alongside the other permanent members of the UN Security Council. Previously referred to by U.S. Special Envoy Steve Witkoff as the “guidepost” for future negotiations, Russian Foreign Minister Sergey Lavrov recently argued that the draft protocol should serve as the basis for security guarantees for Ukraine. According to Russian state-owned news agency RIA, Lavrov said on August 20 that “Russia agrees that security guarantees for Ukraine be provided on equal basis with the participation of countries such as China, the USA, Britain, and France.” Later that day, Ukrainian President Volodymyr Zelenkyy dismissed the premise. As reported by the Kyiv Post, Zelenskyy outlined two reasons why China could not be a security guarantor after the war: “First, China did not help us stop this war from beginning. Second, China helped Russia by opening the drone market.” He added that China demonstrated its unreliability when it failed to act against the Russian occupation of Crimea in 2014, despite being a signatory of the Budapest Memorandum.

When asked for the Chinese response to Lavrov’s and Zelenskyy’s comments, Ning repeated China’s stated position, sidestepping the question of China’s potential involvement postwar. She stated that China “has always held an objective and just position . . . [and] stands ready to play a constructive role” to reach a political settlement. However, a report by German newspaper Die Welt on August 24 indicated that China is prepared to support a peacekeeping mission. According to unnamed European officials, Chinese government sources signaled that the country would be willing to supply Ukraine with peacekeeping forces, provided they were deployed under a UN mandate. The Chinese Foreign Ministry quickly denied the report’s validity, reiterating that China’s position on the Russia-Ukraine war remains “consistent and clear.” On August 29, Zelenskyy expressed his frustration with China’s role in the war, explicitly calling on its leaders to respond to the most recent Russia strikes on Kyiv that killed at least fourteen people. On X, Zelenskyy posted, “We expect a reaction from China to what is going on. China has repeatedly called for not expanding the war and for a ceasefire. Yet this is not happening because of Russia.”

China Rejects U.S. Pressure to Stop Russian Oil Purchases: In late July, China’s Foreign Ministry unequivocally rejected the U.S. demand to halt its purchase of Russian oil. Following two days of negotiations to reach a trade agreement in Stockholm, Sweden, the ministry posted on X that “China will always ensure its energy supply in ways that serve our national interests . . . [and] will firmly defend its sovereignty, security, and development interests.” The post came in reaction to threats made by Trump earlier in July that the United States will impose 100 percent tariffs on Russia’s key trading partners if a peace agreement is not reached in the Russia-Ukraine war. As the largest importer of Russian oil, China is under pressure to comply with U.S. demands. Between January 2023 and January 2025, China imported more than $150 billion worth of Russian oil, allowing Russia to continue generating oil revenue despite being under heavy sanctions.

China has faced global criticism for maintaining its economic support for Russia throughout the Russia-Ukraine war; it remains unfazed by the international backlash, however. In July, China-Russia trade reportedly hit a year high of $19.14 billion amid U.S. tariff threats. Chinese officials have also publicly rebuked efforts to curb Chinese-Russian economic relations. In late July, Chinese envoy to the United Nations Geng Shuang slammed U.S. accusations during a meeting of the UN Security Council that China provided military support to Russia. Shuang argued that “[the] parties to the conflict are not under Security Council sanctions. China has normal trade relations with Russia and Ukraine. By doing so, it does not violate international law or breach its international obligations.”

On August 8, the Chinese Foreign Ministry continued to push back against criticism, stating that it is “legitimate and lawful for China to conduct normal, economic, trade, and energy cooperation with all countries around the world, including Russia.” The day prior, Russian and Chinese media sources quoted spokesperson for the Chinese Embassy in the United States Liu Pengyu as stating that any U.S. attempt to force China to abandon Russia would not succeed. Indeed, China appears to have increased imports Russian oil due to India’s pause on Russian oil purchases. Analysts indicated that Chinese refineries secured fifteen cargoes of Russian oil for delivery in October and November. The cargoes are reportedly being shipped from ports that typically supply India. Relatedly, a recent report indicated that a Chinese state-run terminal appeared to take a shipment of liquified natural gas (LNG) from a Russian LNG export plant currently under U.S. sanctions. Although Trump has recently downplayed the tariff threat, a bipartisan bill introduced in August is circulating in the U.S. Congress that seeks to sanction Chinese entities supporting Russia’s defense industry.

China, Russia Conduct Annual Naval Exercises: During the first week of August, China and Russia held joint naval drills, named Maritime Interaction 2025, in the Sea of Japan (also known as the East Sea). The exercises included artillery firing, anti-submarine and air-defense missions, and joint search-and-rescue operations at sea. The active phase of the drills occurred just two days after Trump responded to former Russian President Dmitry Medvedev’s “highly provocative” statements by ordering the redeployment of two nuclear submarines. On August 5, Chinese Y-8 anti-submarine aircraft and Il-38 planes from Russia’s Pacific Fleet specifically practiced detecting and destroying an enemy submarine, according to Russia’s Defense Ministry.

Shortly after the exercises, the Russian Pacific Fleet’s press service announced the formation of Chinese-Russian joint naval patrols. According to the statement, the objectives of the patrols were “strengthening naval cooperation between Russia and China, maintaining peace and stability in the Asia-Pacific region, monitoring the marine area, and protecting the maritime economic activities of the Russian Federation and the PRC [People’s Republic of China].” A visible manifestation of their “no-limits” strategic partnership, China and Russia’s continued naval cooperation came in response to the growth of U.S. military involvement in the region. The mission, which ended August 25, marked the fifth joint naval patrol between China and Russia since the launch of such operations in 2021. Typically limited to surface vessels, the Russian Pacific Fleet confirmed on August 27 that the operation included their first-ever joint submarine patrol, which involved diesel-electric submarines. Both countries are working to expand their submarine fleets, in addition to modernizing their naval capabilities, and plan to conduct further drills.

Ukraine Sanctions Chinese Support for Russian Drone Industry: On August 17, Zelenskyy signed a presidential decree to sanction individuals and companies linked to Russia’s drone industry. The decree identified fifty-five companies from Belarus, China, and Russia, in addition to thirty-nine Russian nationals. The targeted companies primarily supply Russia with dual-use technologies. Zelenskyy’s action came as Ukraine also reduced its reliance on Chinese-made components and manufacturing in its own drone industry. A report from the Kyiv Independent indicates that new Ukraine-based companies such as Motor-G, Ukraine’s largest producer of electric drone motors, as well as smaller component- and drone-manufacturing workshops, are rapidly developing their capabilities. Although they cannot fully decouple from China in the near future, they are slowly making strides toward that end.

Foreign Fighters Battle Alongside Russia in Ukraine: On August 4, Zelenskyy claimed foreign “mercenaries” from China are fighting alongside the Russian military in Ukraine. According to Zelenskyy, frontline commanders in the Kharkiv region of Ukraine reported engagements with fighters from China, Pakistan, Tajikistan, Uzbekistan, and several African countries. Zelenskyy has accused Russia of recruiting Chinese citizens in the past, claims which Russia has repeatedly denied. In previous months, several Chinese citizens were also reportedly captured in Ukraine.
