US says 'in Europe's best interest' to cooperate on fuel supply

The United States told Europe on Thursday to cooperate with Washington's efforts to lower diesel prices, while a top EU official said a US export ban of the fuel would be "unexpected."

"It is in Europe's best interest to work with the United States as we pursue multiple pathways to boost the supply of refined products and lower costs for consumers," a US official told AFP.

Reports said the Trump administration wanted France and Germany in particular to tap their strategic reserves of diesel to try to curb prices sent soaring by the US war on Iran.

The US is piling on pressure to get European help with fuel costs, with US President Donald Trump on Wednesday floating the possibility of banning diesel exports.

High energy costs loom as a threat to Trump's Republican party in next month's midterm elections.

Still, EU trade chief Maros Sefcovic told reporters Thursday that any move by the US to ban diesel exports would be "unexpected for Europeans."

He spoke on the sidelines of a two-day G20 trade ministers' gathering in Milwaukee, after meeting with Trump's top trade official Jamieson Greer.

Sefcovic told reporters that he did not go into details with Greer on energy exports.

But the transatlantic partners "decided to stay in close touch to avoid any surprises here," he said.

"It would have very dramatic consequences for our economic performance," Sefcovic said of any potential diesel export ban.

France's minister delegate for international trade, Nicolas Forissier, told AFP in Milwaukee: "I can't imagine that there will be a ban."

He stressed the importance of diesel to the United States and European countries, adding both sides will "try to find solutions."

"In France, we'll try to find balanced solutions all over the world," Forissier added. "If not with the Americans, it will be with other countries."

Trump on Wednesday said he was still considering a possible ban on US diesel exports, while adding that he thought it could ultimately cause gasoline prices to rise.

"I'm thinking about it," Trump told reporters in the Oval Office.

Speaking alongside Trump, US Energy Secretary Chris Wright said Wednesday that the world would "hear announcements from our friends in Europe" to push diesel prices down.

Asked about a release from strategic reserves, the French presidency said no such demand had been made when Emmanuel Macron and Trump met on the sidelines of the UN General Assembly last week.

Macron would also soon convene a video meeting of G7 leaders "to make progress on the various levers that can be used to address the rising fuel prices... including coordination on releasing reserves."

Macron announced on September 18 a plan for such a meeting. The G7 gathering is expected in mid-October, according to Macron's press office.

Average US diesel prices have surged to $6.39 a gallon from $3.70 a gallon a year ago.

Fuel prices have caused living costs to soar, leaving Trump's Republican Party fearing it could lose control of Congress in November's midterm elections.
