China–Iran relations

Chinese–Iranian relations (Chinese: 中国–伊朗关系, Persian: روابط ایران و چین) refer to the economic, political, and social relations between the People's Republic of China and the Islamic Republic of Iran. In modern times, official diplomatic relations were first established in 1937 between the Republic of China and Pahlavi Iran. The two civilizations had a history of cultural, political and economic exchanges along the Silk Road since at least 200 BCE and possibly earlier.

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