The Hong Kong-registered firm China Concord Petroleum Co (CCPC) has obtained at least 14 oil tankers over the past year to transfer Iranian and Venezuelan petroleum to China, according to industry and official sources in China, Venezuela, and Iran. The tankers are together capable of holding about 28 million barrels of oil. CCPC provides Iranian petroleum to six independent Chinese refineries colloquially known as "teapots." Iranian officials described CCPC as a key interlocutor in Iran's export of oil to China, which averaged 557,000 barrels per day between November 2020 and March 2021. Iran's total crude oil exports were over 600,000 barrels per day in June 2021, according to a Reuters survey. In 2019, the United States sanctioned CCPC for violating U.S. sanctions on Iran's petroleum industry.
