Was the attempt to reach an agreement between Iran and America mediated by Oman and China's guarantee? Xinhua News Agency announced that China and Oman agreed to encourage the US and Iran to embrace peace options, return to the Islamabad Memorandum and resume talks. Oman was left out of the mediation process led by Pakistan and Qatar, and faced US accusations that it was too close to Tehran. An Asian source told the Al-Mayadeen reporter in Beijing: The Sultan of Oman's trip is not ceremonial in any way and the issue of bilateral relations was the second priority of the discussed cases. An informed source told Al-Mayadeen reporter: The priority of this trip is to test Oman's new mediation between Tehran and Washington with China's full economic and security guarantee. One of the reasons for the failure of the mediation of Pakistan and Qatar is the activation of the "Mecca Agreement" and the attempt to separate the case of Yemen from Iran. The failure of the mediation of Pakistan and Qatar, which China tried to succeed, has reasons that include the reduction of trust and the activation of the "Mecca Agreement". From China's perspective, Oman has shown sincerity in its mutual relations, which has been demonstrated in the case of Yemen, including following up on the 1,600 prisoner exchange agreement. After the failure of the mediations of Pakistan and Qatar, the need for an "Omani canal" is felt again. This source announced that the "Omani Canal", secretly and powerfully supported by China, had made "unprecedented progress" before Washington returned to the war and ended it. This source announced that "Oman Channel" is the same channel that was behind the indirect negotiations between Washington and Tehran in February 2026. According to this source, from China's point of view, Oman is the only country in the Persian Gulf that keeps its communication channels open with all parties and operates on several fronts. The Al-Mayadeen reporter in Beijing, citing an Asian source, announced: The Iranian ambassador, along with an accompanying delegation, arrived at the scene an hour before the meeting between the Sultan of Oman and the President of China. An Asian source told the Al-Mayadeen reporter in Beijing: Iran's ambassador attended a separate meeting with Chinese officials on the second floor of the People's Hall.
