“Mr. Trump sends every day a new message that creates uncertainty in the market,” Bijan Namdar Zanganeh said in an interview with national television.
Trump on Wednesday said the Organization of Petroleum Exporting Countries has pushed fuel prices higher, and urged Saudi Arabia to pump more if it wanted Washington’s protection in the region, Reuters reported.
“Trump’s order to OPEC members to increase production is a great insult to those governments and nations, and destabilizes the market.”
Zanganeh called the tension between Tehran and Washington a “trade war” and said it had not led to changes in Iranian oil production and exports.
Iran, OPEC’s third-largest producer, is facing US sanctions on its oil exports that are prompting some buyers to cut purchases.
Washington said in May that it was walking away from an international deal on Iran’s nuclear program, and said it would impose fresh sanctions on Iran’s energy sector.
South Korea halted all Iranian oil shipments in July for the first time in six years amid US pressure.
The EU, once Iran’s biggest oil importer, has promised to try and keep the 2015 nuclear deal alive without the United States, by trying to keep oil and investment flowing.
Foreign ministers from the five remaining signatory countries offered a package of economic measures to Iran on Friday to counter the US sanctions, but Tehran said the package did not go far enough.
“I have not seen the package, personally, but our colleagues in the Foreign Ministry who have seen it were not happy with its details,” Zanganeh said.
President Hassan Rouhani said on Tuesday that Iran could disrupt oil shipments from neighboring countries if Washington pressed ahead with its goal of forcing all countries to stop buying Iranian oil.
Commenting on Rouhani’s remark, Zanganeh said the president’s stance on this issue was clear.
