After his visit to China last month, during which he met with President Xi, Raisi said his trip had been "successful and fruitful".

Khoshcheshm said, "On his recent visit to Beijing, President Raisi asked his Chinese counterpart to take a more assertive stance and mediate between the two sides after Iran and Saudi Arabia had four rounds of talks in Baghdad at the initiative of the Iraqi government."

Also professor at the Fars News Media Faculty at the University of Applied Science and Technology in Teheran, Khoshcheshm said, "The latest round of (Saudi-Iranian) talks demonstrated a more assertive stance by the Chinese on the world stage."

Wang Jin, associate professor at the Institute of Middle East Studies at Northwest University in Xi'an, Shaanxi province, said China plays a crucial external role in the Middle East, which is what countries in the region want to see.

The tripartite statement highlights the importance of dialogue in achieving peace, Wang said, adding, "China's concept of peaceful diplomacy will increasingly gain recognition globally, and will also make significant contributions to regional and international peace."

Mehmood Ul Hassan Khan, executive director of the Center for South Asia & International Studies in Islamabad, Pakistan, said China's increased presence in the Middle East will create "win-win" situations for all.

"It seems that China will also continue to play a constructive role in properly handling regional and international (disputes) in accordance with the wishes of all countries, and demonstrate its responsibility as a major power," he added.
