Iranian Foreign Minister Mohammad Javad Zarif stressed that the internal disputes in US over the nuclear deal with Tehran is not related to the Islamic Republic.

"As we have stated since the beginning, we consider the US administration responsible for implementing the agreement,” Zarif told reporters on Sunday afternoon in New York where he is due to participate in the Nuclear Nonproliferation Treaty, or NPT, Review Conference.

“Internal problems and conflicts in the US are not related to us and to the implementation of the agreement, and based on the international laws,” the top Iranian diplomat said, stressing that the countries' internal problems “don’t exempt them from implementing their undertakings and this is the main framework that we attach importance to.”

Zarif also reiterated the necessity for the termination of all sanctions on the same day that the possible nuclear agreement between Tehran and the world powers comes into effect.

"We have said since the first day that agreement and sanctions aren’t compatible," he said according to Fars news agency.

After nine days of hard work in Lausanne, Switzerland, Iran and the G5+1 reached an understanding on April 2 which laid the ground for them to start drafting the final nuclear deal over Tehran's nuclear energy program ahead of a July 1 deadline.
