The top diplomats from the United States and Iran will discuss the conflict in Yemen on Monday, U.S. Secretary of State John Kerry said, as he urged 'everybody do their part' to reduce violence and encourage negotiations, Reuters reported.

'Yemen's future should be decided by Yemenis ... not by external parties and proxies,' Kerry said, adding he expected the conflict to come up in his talks later in the day with Iranian Foreign Minister Mohammad Javad Zarif.

It will be the first meeting between the top Iranian and US diplomats since Iran and the P5+1 - the United States, France, Britain, Russia and China plus Germany – reached a mutual understanding on the parameters of a comprehensive agreement over Tehran’s nuclear program in the Swiss city of Lausanne on April 2.

Iran and the P5+1 countries ended their latest round of talks at the deputy and expert levels in Vienna, Austria, on April 24. The three-day talks were held with the goal of drafting the text of the Joint Comprehensive Plan of Action (JCPOA) based on the mutual understanding reached in Lausanne.

Zarif is also scheduled to hold separate meetings with EU foreign policy chief, Federica Mogherini, and some foreign ministers of the P5+1 group.

Zarif said Monday the US government is responsible to implement the nuclear deal with Iran and that its internal quarrels do not free it from fulfilling its international commitments.

Speaking to IRNA upon arrival in New York, he said he will attend the Review Conference of NPT which is held at five-year intervals at UN Headquarters to discuss the three major parts of the treaty and reach a final binding document.

Noting that most of the problems connected with the final document have not been solved yet, Zarif said Iran, as the chair-state of Non-Alignment Movement (NAM), will try to follow the positions of NAM which in many cases are the same as those of the Islamic Republic of Iran.

Iran's foreign minister was the first state party to the NPT to address its 190 signatories at the United Nations headquarters in New York on behalf of the 118 members of the Non-Aligned Movement that have signed the NPT as the world's benchmark disarmament pact.

Zarif said in his address that the Non-Aligned Movement considers nuclear disarmament as its highest priority and reiterates once again that the continued existence of nuclear weapons poses the greatest threat to humanity.

“We remain extremely concerned at their possible use or threat of use and are convinced that their total elimination is the only absolute guarantee against such use or threat of use,” Zarif said.
