The US said it will increase pressure on China to stop buying Iranian oil, as the White House seeks to enforce sanctions aimed at curbing the Islamic Republic’s nuclear activities, Report informs referring to Bloomberg.

“China is the main destination of illicit exports by Iran” and talks to dissuade Beijing from such purchases will be “intensified,” Robert Malley, the Biden administration’s special envoy for Iran, told Bloomberg Television on January 23.

The US tightened sanctions on Tehran and its petroleum exports in 2018 after pulling out of an agreement aimed at containing its atomic program. In response, Iran has ramped up uranium enrichment.

Iranian shipments of crude oil and refined products have surged in recent months. Much of the oil appears to be heading to China, the world’s biggest importer, and disguised as coming from Malaysia.

He reiterated comments from other US officials that talks with Iran on reviving the nuclear agreement from 2015 have largely broken down. The US is concentrating on stopping Iran from using violence against protesters at home and on preventing it from supporting Russian operations in Ukraine, Malley said.
