China–Sudan relations refer to the bilateral relations between the People's Republic of China and the Republic of Sudan. China is currently one of Sudan's largest trade partners, importing oil and exporting low cost manufactured items as well as armaments into the country. Both states enjoy a very robust and productive relationship in the fields of diplomacy, economic trade, and political strategy. They formally established diplomatic relations on January 4, 1959 when Sudan formally recognized the sovereignty of the People's Republic of China and have since become close global allies, supporting each other in times of internal crises and international controversy such as during the Second Sudanese Civil War, the Darfur Crisis, and the Xinjiang Conflict. China continues to provide massive support to Sudan by developing its oil resources and supplying millions of dollars in loans, aid, foreign direct investments, and humanitarian assistance. In return, Sudan has become a reliable political and economic ally in the international arena, allowing China to maintain a significant stake in its oil sector.
