President Donald Trump said Wednesday he strongly supports the United Arab Emirates’ decision to leave the international oil cartel OPEC, saying he believes the move will bring energy prices down.

“I think it’s great,” Trump told reporters at the White House after meeting with Artemis II astronauts.

UAE President Sheikh Mohamed bin Zayed Al Nahyan is “very smart,” said Trump, “and he probably maybe wants to go his own way. That’s a good thing.”

“I think ultimately it’s a good thing for getting the price of gas down, getting oil down, getting everything down,” Trump said, adding, “they’re having some problems in OPEC.”

Oil prices have spiraled upwards since the U.S. and Israel launched a war with Iran on Feb. 28.
