Kina: Vill fördjupa ryskt samarbete på alla plan

China–Russia relations, also known as Sino-Russian relations, are the international relations between the People's Republic of China and the Russian Federation. Diplomatic relations between China and Russia improved after the dissolution of the Soviet Union and establishment of the Russian Federation in 1991. American scholar Joseph Nye states: With the collapse of the Soviet Union, that de facto US-China alliance ended, and a China–Russia rapprochement began. In 1992, the two countries declared that they were pursuing a "constructive partnership"; in 1996, they progressed toward a "strategic partnership"; and in 2001, they signed a treaty of "friendship and cooperation." 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. The two countries 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'.
