The trilateral statement issued on Friday said Saudi Arabia and Iran had held talks to resolve their differences through dialogue and diplomatic means, to abide by the purposes and principles of the Charters of the United Nations and the Organization of Islamic Cooperation, and to follow international regulations and practices.

The two countries also extended their appreciation and thanks to Chinese leaders and the Chinese government for hosting, supporting and contributing to the success of the talks, the statement said. They also thanked Iraq and Oman for hosting several rounds of dialogue in 2021 and last year.

Saudi Arabia and Iran have a long and complex history of rivalry primarily fueled by religious, political and economic differences, as well as a struggle for regional influence and power. They have also been involved in conflicts in Syria and Yemen.

Quest for stability

Deniz Istikbal, an economics researcher at the Foundation for Political, Economic and Social Research, a think tank in Ankara, Turkiye, said that China, which has invested more than $200 billion in Western Asia, has taken a stand for stability in the region.

"This stand draws attention to bilateral relations and cooperation. Compared with other players, China is striving to stabilize the region," Istikbal said.

"As in Africa, China's power and influence are growing in the Middle East. However, there are too many competing players in the region. As a global player, China stands apart from others by taking a stand for diplomacy."
