China–Russia relations

China and Russia established diplomatic relations after the dissolution of the Soviet Union in 1991, and share one of the world's most important foreign relationships. Both nations share interest in energy cooperation, military ties, global stability, and geopolitical alignment in challenging the West.

The two countries share a land border which was demarcated in 1991, and they signed the Treaty of Good-Neighborliness and Friendly Cooperation in 2001, which was renewed in June 2021 for five more years. On the eve of a 2013 state visit to Moscow by Chinese leader Xi Jinping, Russian President Vladimir Putin remarked that the two nations were forging a special relationship. China and Russia have enjoyed close relations militarily, economically, and politically, while supporting each other on various global issues. Commentators have debated whether the bilateral strategic partnership constitutes an alliance. Russia and China officially declared their relations "Not allies, but better than allies", although Vladimir Putin reiterated that their relationship is a de facto alliance. Ties have continued to deepen after Russia's invasion of Ukraine in 2022, with Russia increasingly becoming dependent on China since it was hit with large-scale international sanctions. Russian coal exports came under particular pressure in Europe due to the combination of energy transition and sanctions over Ukraine, causing Russia to heavily increase trade on coal exports to China and other Asian countries. The annual trade between China and Russia was 240 billion dollars as of 2023.
