Representatives of China, Russia and Iran called Friday for an end to U.S. sanctions on Iran over its rapidly advancing nuclear program and a restart to multinational talks on the issue. The talks are the latest attempt to broach the matter and come after U.

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.

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.
