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 and Russia joined Iran in denouncing US sanctions and backed efforts to restore a landmark nuclear deal with Tehran that President Donald Trump abandoned in his first term and now wants to replace.

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.
