Representatives of China, Russia and Iran have called for an end to U.S. sanctions on Iran over its rapidly advancing nuclear program and a restart to multinational talks on the issue.

Beijing sought to position itself as a key player in negotiations with Iran over its nuclear program, as President Trump called for talks with Tehran.

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.
