The Chinese president pledged to enhance cooperation with Iran following a phone call with his Iranian counterpart on Friday.
"China is willing to strengthen cooperation with Iran within Shanghai Cooperation Organization (SCO) and other frameworks," Xi Jinping told his Iranian counterpart Ebrahim Raisi in a phone call, the Chinese daily Global Times reported.
The phone call was held while the SCO is holding a summit of its foreign ministers in Tashkent, the capital of Uzbekistan. Iran is a member of the SCO.
Xi said China supports the "independent development paths" of Middle Eastern countries.
China and Iran have raised their bilateral relations to the strategic level and have also signed a deal under which Beijing will invest more than $400 billion in Iran in the next 25 years.
Earlier in the day, Xi also spoke to his Polish counterpart Andrzej Duda.
Xi said that China sees Poland as a "preferred partner in Europe and is willing to increase political trust and continue to improve the comprehensive strategic partnership."
The duo also discussed the situation in Ukraine.
