DUBAI - Iran will continue fuel shipments to Venezuela if Caracas requests more supplies, the Iranian Foreign Ministry spokesman said on Monday, despite Washington’s criticism of the trade between the two nations, which are both under US sanctions.

Defying US threats, Iran has sent a flotilla of five tankers of fuel to the South American oil-producing nation, which is suffering from a gasoline shortage

“Iran practises its free trade rights with Venezuela and we are ready to send more ships if Caracas demands more supplies from Iran,” Abbas Mousavi told a weekly news conference broadcast live on state TV.

Defying US threats, Iran has sent a flotilla of five tankers of fuel to the South American oil-producing nation, which is suffering from a gasoline shortage.

Seeking to deter further shipments of Iranian fuel to Venezuela, Washington is monitoring the supply. It has warned governments, seaports, shippers and insurers that they could face measures if they aid the tankers.

According to Refinitiv Eikon on Sunday, two Iranian tankers that delivered fuel to Venezuela as part of the flotilla have begun to sail back, as the government in Caracas prepares stations to begin charging for the gasoline.
