China–Iran relations

Chinese–Iranian relations (Chinese: 中国–伊朗关系, Persian: روابط ایران و چین) refers to the economic, political, and social relations between the People's Republic of China and the Islamic Republic of Iran. Official diplomatic relations were first established in 1937. The two old civilizations had a history of cultural, political and economic exchanges along the Silk Road since at least 200 BC and possibly earlier. They have developed a friendly, economic and strategic relationship.

In March 2021, Iran and China signed a 25-year cooperation agreement that will strengthen the relations between the two countries and that would include "political, strategic and economic" components.
