FNA- Chinese Foreign Ministry Spokeswoman Hua Chunying underlined that the western countries should remain committed to the nuclear agreement signed with Iran in July 2015.

"Beijing will have close cooperation with all the beneficiaries for the full implementation of the nuclear agreement," Chunying said.

Her remarks came after Iranian Deputy Foreign Minister Seyed Abbas Araqchi underlined that the nuclear talks with Washington have ended and the nuclear deal is no more open to renegotiation.

"Except some technical issues, we don�t have any negotiations with the Americans on the Joint Comprehensive Plan of Action (JCPOA) and the future of the agreement," Araqchi told reporters in a press conference in Tehran and after talks in Vienna with the negotiators from the six world powers over the latest developments with regard to the nuclear deal.

Noting that the new US president can make any decision he wants about the nuclear deal, he said, "The JCPOA will not be open to negotiations at all."

"Our nuclear talks with the US have ended. We will not enter political negotiations with neither the current nor the future US administration. The JCPOA is a finished case in our view," Araqchi stressed.

He also said that Iran views the extension of Iran Sanctions Act (ISA) by the US as a new sanction and violation of the JCPOA.
