China has confirmed it imported no Iranian crude in June even as the two countries are reportedly finalising a $400bn energy and transport deal.

According to customs data cited by various media outlets, the world’s largest crude importer did not receive any crude from Iran last month, compared with 60,000 barrels per day (bpd) in May.

Platts said this zero import had never occurred since it began tracking General Administration of Customs data in January 2007.
