China’s Foreign Minister Wang Yi and his Iranian counterpart Mohammad Javad Zarif had phone conversation during which they discussed  the  recent statement of the US top leadership regarding the Iranian nuclear deal, TASS reported.

"The corresponding international agreements on this issue have been officially approved by the UN Security Council, and each party is responsible for observance of this agreement," Wang Yi noted.

The Chinese diplomat emphasized that this document plays an important role as it  contributes to non-proliferation of weapons of mass destruction in the world.

"This agreement is still accurately implemented, however new imminent ambiguous factors should be taken into account," he added.

The day before, US President Donald Trump said that the US will stop the participation in the Iranian nuclear deal unless it was amended.
