DUBAI, UNITED ARAB EMIRATES -- OPEC, Russia and other oil-producing nations on Sunday finalized an unprecedented production cut of nearly 10 million barrels, or a tenth of global supply, in hopes of boosting crashing prices amid the coronavirus pandemic and a price war, officials said.

The cartel and other nations agreed to allow Mexico to cut only 100,000 barrels a month, a sticking point for an accord initially reached Friday after a marathon video conference between 23 nations. They reached the deal just hours before Asian markets reopen Monday as international benchmark Brent crude traded at just over $31 a barrel and American shale producers struggle.

Oil prices have collapsed as the coronavirus and the COVID-19 illness it causes have largely halted global travel and slowed down other energy-chugging sectors such as manufacturing.

Mexico's energy minister said on Twitter that the group of nations agreed to cut 9.7 million barrels a day to begin May 1. Energy officials from other countries shared similar information.

Video aired by the Saudi-owned satellite channel Al-Arabiya showed the moment that Saudi Energy Minister Prince Abdulaziz bin Salman, a son of King Salman, assented to the deal.

"I go with the consent, so I agree," the prince said, chuckling, drawing a round of applause from those on the video call.

But it had not been smiles and laughs for weeks after the so-called OPEC+ group of OPEC members and other nations failed in March to reach an agreement on production cuts, sending prices tumbling. Saudi Arabia sharply criticized Russia days earlier over what it described as comments critical of the kingdom, which finds itself trying to appease U.S. President Donald Trump, a longtime OPEC critic.

Even U.S. senators had warned Saudi Arabia to find a way to boost prices as American shale firms face far-higher production costs. American troops had been deployed to the kingdom for the first time since the Sept. 11, 2001, attacks over concerns of Iranian retaliation amid regional tensions.

"They've spent over the last month waging war on American oil producers while we are defending theirs. This is not how friends treat friends," said Sen. Kevin Cramer, a Republican from North Dakota, before the OPEC+ deal. "Frankly, I think their actions have been inexcusable and they are not going to be easily or quickly forgotten."

U.S. producers have already been reducing output and are on track for a production decline of 2 million to 3 million barrels per day, according to the U.S. Department of Energy. The American Petroleum Institute lauded Sunday's global pact, saying it will help get other nations' state-owned oil production to follow the lead of U.S. producers that are trying to adjust to a "historic drop in demand."

U.S. Energy Secretary Dan Brouillette credited President Donald Trump's leadership for Russia and Saudi Arabia finalizing what he called 鈥渁 historic deal, ending a price war that has caused unprecedented uncertainty in global oil markets.鈥

鈥淲hile the demand disruption caused by COVID-19 and the price war have greatly harmed the industry, I am confident it will soon bounce back stronger than ever before,鈥 Brouillette said in a statement.

Iran's Oil Ministry confirmed the 9.7 million global cut for May and June and said the agreement would have Mexico reduce its output by 100,000 barrels only for those two months. That had been a sticking point for the accord meant to boost global energy prices.

Iranian Oil Minister Bijan Zanganeh also told state television that Kuwait, Saudi Arabia and the United Arab Emirates would cut another 2 million barrels of oil a day between them atop the OPEC+ deal. The three countries did not immediately acknowledge the cut themselves, though Zanganeh attended the video conference.

Nigeria's Petroleum Resources Ministry said in a statement that other planned cuts would stand in the deal, meaning an 8 million barrel per day cut from July through the end of the year and a 6 million barrel cut for 16 months beginning in 2021.

鈥淭his will enable the rebalancing of the oil markets and the expected rebound of prices by $15 per barrel in the short term,鈥 the ministry said in a statement.

Mexico had initially blocked the deal but its president, Andres Manuel Lopez Obrador, had said Friday that he had agreed with Trump that the U.S. will compensate what Mexico cannot add to the proposed cuts.

鈥淭he big Oil Deal with OPEC Plus is done. This will save hundreds of thousands of energy jobs in the United States,鈥 Trump said in a tweet. 鈥淚 would like to thank and congratulate President Putin of Russia and King Salman of Saudi Arabia.鈥

The Kremlin said President Vladimir Putin held a joint call with Trump and Saudi King Salman to express support of the deal. It also said he spoke separately with Trump about the oil market and other issues.

Analysts offered cautious praise.

鈥淭he pure size of the cut is unprecedented, but, then again, so is the impact the coronavirus is having on demand,鈥 said Mohammed Ghulam, an energy analyst at Raymond James.

But Ghulam and others worried it may not be enough.

鈥淭his is at least a temporary relief for the energy industry and for the global economy. This industry is too big to be let to fail and the alliance showed responsibility with this agreement,鈥 said Per Magnus Nysveen, the head of analysis at Rystad Energy. 鈥淓ven though the production cuts are smaller than what the market needed and only postpone the stock building constraints problem, the worst is for now avoided.鈥
