António Guterres made the request in a statement issued on Thursday by his Spokesperson to mark 50 years since the Non-Proliferation Treaty came into force.
Today is the #NPT’s golden anniversary. For five decades it has been a pillar of international #security and a catalyst for the pursuit of a world free of #nuclearweapons. #NPT2020 Review Conference is the chance to make sure it remains so.

He congratulated the States Parties on this milestone: “Throughout the past half century, the NPT has served as an essential pillar of international peace and security, and the heart of the nuclear disarmament and non-proliferation regime. It has conferred tangible security benefits on all its States parties”, the statement said.
The Non-Proliferation Treaty seeks to prevent the spread of nuclear weapons and weapons technology and to promote co-operation in the peaceful uses of nuclear energy.
It represents the only binding commitment to the goal of disarmament, by the five States which officially stockpile nuclear weapons: China, France, Russia, the United Kingdom, and the United States.
Overall, 191 countries have signed onto the treaty, which opened for signature in 1968 and was extended indefinitely in 1995.
Parties will meet at UN Headquarters in April for their latest Review Conference, which takes place every five years.
They were unable to reach agreement on the substantive part of the draft final document at their last meeting in 2015.
At the upcoming conference, countries will identify areas and means through which further progress can be made, according to the UN statement.
“The Secretary-General calls on States parties to make the most of this opportunity to strengthen international peace and security through the promotion of non-proliferation of nuclear weapons and nuclear disarmament, as well as measures to strengthen implementation of the NPT and achieve its universality”, it concluded.
