Geng's statement comes after a meeting of the JCPOA participants on the sidelines of the UN General Assembly in New York earlier this week.
The JCPOA was signed in 2015 by Iran, the European Union and the P5+1 group of countries — China, Germany, France, Russia, the United Kingdom, and the United States. The deal stipulated the gradual easing of sanctions on Iran in exchange for Tehran maintaining the peaceful nature of its nuclear program.
US President Donald Trump announced in early May that the United States would pull out from the deal and restore wide-ranging sanctions on Iran.
