China and Russia are both permanent members of the U.N. Security Council, along with France and Britain, that took part in the original 2015 Iran nuclear deal preliminary framework agreement. Trump withdrew America from the accord in 2018, setting in motion years of tensions in the wider Middle East.

China will hold a meeting on Friday in Beijing with Russia and Iran on the Iranian "nuclear issue", its foreign ministry said, with both nations sending their deputy foreign ministers.

China, Iran and Russia called for diplomacy over “pressure and threats” and an end to “all illegal unilateral sanctions” following talks on Tehran’s nuclear program Friday in Beijing, Chinese state media said.
