The US has warned that it will impose sanctions on China if Asia’s largest economy continues to import crude oil from Iran.

A US Department of State spokeswoman said yesterday that sanctions would be placed on any country that continues to import Iranian crude in violation of US sanctions.

"We're going to zero, and countries that don't abide by US sanctions will face repercussions for not abiding by US sanctions," said Department of State spokeswoman Morgan Ortagus during a briefing held on Thursday.
