"Today all parties have agreed to come back to activate the eighth round of negotiations even in (the) Christmas and New Year's holiday. This in itself fully shows a greater sense of urgency on the part of all parties concerned," Wang Qun, China’s ambassador to the United Nations institutions headquartered in Vienna, Austria, which includes the International Atomic Energy Association (IAEA) nuclear watchdog, told reporters on Monday. China is just one of several parties to the 2015 Joint Comprehensive Plan of Action (JCPOA) deal, who also include Russia, France, Germany, the UK, the European Union, the US, and Iran. However, since Tehran refuses direct negotiations with Washington, which is responsible for shredding the deal in 2018, the deal’s other parties have headed up the talks.
Last month, Iranian Supreme Leader Ayatollah Ali Khamenei announced that Tehran is in "no hurry" to return to its obligations under the 2015 Iran nuclear deal, and is prepared to wait until the US lifts its illegal sanctions against the Islamic Republic. Iranian Deputy Foreign Minister Abbas Araqchi has stated that a possible US decision to rejoin the 2015 nuclear deal, also known asthe Joint Comprehensive Plan of Action (JCPOA), does not require any talks. Speaking to the deal's remaining signatories during a virtual meeting on Friday, Araqchi added that "Iran will suspend its steps [scaling back compliance with the deal's terms] as soon as [US] sanctions are lifted and this is verified".
