Iran's Foreign Minister Mohammad Javad Zarif left Tehran to New York on April 18 to participate in the UN Climate Summit, Mehr reported Apr. 18.
Zarif reportedly is accompanied by Abbas Araqchi, and Majid Takht Ravanchi who are the top nuclear negotiators.
Mehr said that Zarif will negotiate the Joint Comprehensive Plan of Action (JCPOA) with his American counterpart John Kerry in New York.
Iran and P5+1 (US, UK, France, Russia, China + Germany) implemented JCPOA in mid-January. However, Iran asks US to pave the path for cooperation of non-American banks with Tehran.
Washington says that providing the access of Iran to the American financial system has not been included in JCPOA.
A landmark agreement will be signed by 155 countries to tackle the climate change at a ceremony at the UN headquarters Apr. 22, the UN said Friday.
The Paris agreement, achieved last year, will take effect 30 days after at least 55 countries, accounting for 55 percent of global greenhouse gas emissions, deposit their instruments of ratification or acceptance with the secretary-general, AP reported on April 15.
The agreement sets out a global action plan to put the world on track to avoid dangerous climate change by limiting global warming to well below 2C.
The agreement is due to enter into force in 2020.
