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.

China has called for “illegal” sanctions against Iran to be lifted after the country’s leaders met in Beijing. Representatives of Russia and Iran were hosted by China this week as the three countries “exchanged views on the Iran nuclear issue and other issues of common concern,” according to Chinese State Media.

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.
