Russian Foreign Ministry Oleg Rozhkov appreciated Tehran's patience in honoring its commitments despite continuous provocations.
The patience, peace and responsible approach of Iran in the implementation of its commitments to JCPOA must be appreciated, said Rozhkov in his speech at the Preparatory Committee for the 2020 Review Conference of the Parties to the Treaty on the Non-Proliferation Treaty (NPT) on Tuesday.
Success in implementation of the deal by Tehran shows its valuable share to strengthen the world's views on non-proliferation of nuclear weapons.
He hailed International Atomic Energy Agency's unbiased and professional approach in its reports regarding the Joint Comprehensive Plan of Action (JCPOA).
The IAEA verified Iran's commitment to the international deal for the fourth consecutive year and has repeatedly announced that Iran has provided the Agency's inspector with access to all of its nuclear facilities.
He criticized the US for withdrawing from the Intermediate-Range Nuclear Forces Treaty and said that the move will return the world to where it was 30 years ago.
It is unclear that what will happen in two years, with the expiration of Strategic Arms Reduction Treaty, he said.
He added that the US withdrawal from international treaties is a sign of Washington's irresponsible policies.
The US left the nuclear agreement last May and restored two rounds of economic sanctions on Iran. Washington is also trying to bring Iran oil sales to zero by not renewing the waivers to the eight countries, the customers of Iranian crude.
Despite the US withdrawal, Iran has stuck to the agreement as verified by 14 consecutive reports of the International Atomic Energy Agency (IAEA). Russia, China, Germany, France and the UK have said they will stay in the deal as long as Iran remains there.
The three European signatories, also known as the E3, put in place in January a Special Purpose Vehicle (SPV), called the Instrument in Support of Trade Exchanges (INSTEX), to help trade of non-sanctioned goods with Iran. However, the mechanism has yet to operate.
