Saudi Arabia and Iran agreed to reestablish diplomatic relations and reopen their embassies within two months following years of tensions between the two countries in a China-brokered deal.

“Generally speaking, we welcome any efforts to help end the war in Yemen and de-escalate tensions in the Middle East region,” John Kirby said. “De-escalation and diplomacy together with deterrence are key pillars of the policy President Biden outlined during his visit to the region last year,” they added.

Kirby added that, while the US welcomed the deal, Washington remained “skeptical” about whether Iran would “meet their obligations.”

The UAE said on Friday it welcomed the agreement, and said it “valued” China's role in the negotiations.

“We believe in the importance of positive communication and dialogue between the countries of the region to consolidate the concept of good neighborliness,” senior government official and advisor to the UAE president Anwar Gargash said.

He also welcomed the reactivation of the security cooperation agreement between the two countries and the general cooperation agreement in the fields of economy, trade, investment, technology, science, culture, sports and youth.

Al-Thani further expressed Qatar's aspiration that this step “contribute to enhancing security and stability in the region, and meet the aspirations of the peoples of the two countries for the benefit of the whole region.”

Iraq and Oman also both welcomed the announcement of the resumption of relations, according to state news agencies in both countries.

Oman “welcomed the trilateral statement on resumption of diplomatic ties between Riyadh and Tehran,” a statement carried by Oman News Agency said, while Iraq welcomed “turning a new page” between Iran and Saudi Arabia, its state news agency said.

“This is a win-win for everyone and will benefit regional and global security,” Omani foreign minister Badr Albusaidi said. “We hope in the longer term there’s also potential for increasing economic benefits for all,” he added.
