Investing.com -- The United Arab Emirates has intensified efforts to push for an end to the Iran war, joining Saudi Arabia and Qatar in urging US President Donald Trump to pursue negotiations, according to a Bloomberg report Friday citing people familiar with the matter.

The conversations were prompted by fears that any retaliation from Tehran would plunge Gulf economies into chaos if hostilities resume, the report said. In separate calls with Trump, leaders of the three US allies reportedly said military action won’t achieve America’s long-standing goals with Iran.

Abu Dhabi’s stance indicates a shift for a country that bore the brunt of Iran’s attacks and has been more hawkish than its neighbors toward Tehran.

The UAE, Saudi Arabia and Qatar differ on the kind of diplomatic deal the US should pursue and how tough it should be with Iran. But their outreach to Trump underscores their shared wariness of a repeat of the situation between late February, when Israel and the US launched a war on the Islamic Republic, and a ceasefire in early April.

Iran and Tehran-backed militant groups in Iraq retaliated by firing thousands of drones and missiles across the Gulf, killing scores of people and causing billions of dollars worth of damage to ports and energy infrastructure.

The UAE was frustrated when Saudi Arabia and other Gulf states refused to respond collectively with force against Iran to deter its attacks. Abu Dhabi carried out limited strikes on Iran in coordination with the US and Israel, while Saudi Arabia took similar action separately, reports at the time suggested.

Iran and the US agreed to a truce on April 8 and are exchanging messages via Pakistan about a peace deal. Tehran and Washington have each said they’re ready to resume hostilities and are showing little sign of making concessions.

Trump’s secretary of state, Marco Rubio, on Friday said there was "slight progress" toward a deal. Iranian media made similar comments.

Some Gulf leaders aren’t sure their calls will be heeded and are concerned Israel will convince Trump to attack Iran again. Prime Minister Benjamin Netanyahu has signaled more strikes are necessary to further degrade Iran’s military.

"There’s a 50-50 chance that we will reach an agreement" with Iran, Anwar Gargash, a senior advisor to the UAE’s president, said on Friday. "My worry is that the Iranians have always over-negotiated. I hope they don’t do that this time because the region does need a political solution. Round two of a military confrontation will only complicate things."

Saudi Arabia supports mediation via Pakistan and believes getting Iran to curb its nuclear and ballistic-missile programs can only be resolved through talks.

The kingdom, as well as the UAE, think the US should focus for now on getting Iran to reopen the Hormuz Strait and maintain its naval blockade of Iranian ports to force Iran into conceding on that.

Qatar continues to support the Pakistan-led mediation efforts, the reporsaid. Qatar has consistently advocated for de-escalation for the sake of the region and its people.
