China and Iran have pledged to cooperate to promote the implementation of a comprehensive agreement on Iranian nuclear issue.

Chinese Foreign Minister Wang Yi, at the invitation of his Iranian counterpart, Mohammad Javad Zarif, had a telephone conversation on July 6 with Zarif, in which they exchanged views on China-Iran relations and the implementation of the comprehensive nuclear agreement.

Chinese President Xi Jinping paid a successful state visit to Iran in January and the two countries upgraded their ties to a comprehensive strategic partnership, Wang said, adding that both sides have made positive progress in implementing the consensus reached by the heads of state of the two countries.

Since the comprehensive agreement on the Iranian nuclear issue was reached in July 2015, Iran and the six major world countries—Britain, China, France, Germany, Russia and the United States—have actively made their commitment and the implementation of the agreement goes smoothly, Wang said.

Wang said that he hoped all related parties would continue to shoulder their responsibilities, deepen mutual trust and implement UN Security Council Resolution 2231 as well as the Arak heavy-water project. "China will continue to play a constructive role," he said.

For his part, Zarif said Iran attaches great importance to the fruits Xi's Iran visit has yielded and will work with China to realize the consensus reached by the two heads of state.

The Iranian side speaks highly of the efforts the Chinese side has made to facilitate the Arak reactor's reconstruction, Zarif said, adding that Iran will cooperate with China to enhance the implementation of the comprehensive nuclear deal.
