China Directs Firms to Defy U.S. Sanctions on Iranian Oil, Escalating Tensions
China has instructed its companies to disregard U.S. sanctions related to Iranian oil, marking a significant escalation in the ongoing economic tensions between the two nations. This directive from China's Ministry of Commerce is the first explicit order for Chinese firms to defy such measures, utilizing a sanctions-blocking mechanism introduced in 2021. This move comes in response to the U.S. Treasury Department's warning of potential secondary sanctions against entities involved with 'teapot refineries' in China that process Iranian oil. These refineries, primarily located in Shandong province, are small, privately owned facilities that handle a significant portion of China's sanctioned crude from Iran and Russia. The U.S. has identified these refineries as a critical gap in sanctions enforcement, as they provide substantial revenue streams to the Iranian government.
