The resolution noted the need to hold a conference with a view to developing a legally binding tool for the prohibition of nuclear weapons, which will lead to their complete elimination.
With the risk of nuclear detonation higher than at any time since the end of the Cold War, this treaty is an urgent priority for all countries that believe in a future free of nuclear weapons.
Past year at a United Nations committee meeting, the DPRK voted in favor of the resolution proposing to convene a conference on negotiations of a treaty to ban nuclear weapons. The first stage of the conference will last until March 31 and will be held without Russian Federation, which is opposed to adopting the treaty along with other nuclear powers, including the United States, the UK and France.
Even Japan - the only country to have suffered atomic attacks, in 1945 - voted against the talks, saying the lack of consensus over the negotiations could undermine progress on effective nuclear disarmament.
"I expect that this will take a long time, let's not be naive", Swedish Foreign Minister Margot Wallstrom said at the United Nations last week.
Though a recent missile test failed last week, two USA officials said satellite images suggested the North was ready to executive its sixth underground nuclear test at "any time", CNN reported Friday.
The UN said the conference represents the first multilateral negotiations on nuclear disarmament in more than 20 years. Immediately after this, President Donald Trump tweeted that the USA must greatly strengthen and expand its nuclear capability.
"Regrettably, given the present circumstances, we must say that it would be hard for Japan to participate in this conference in a constructive manner and in good faith", Nobushige Takamizawa, head of Japan's permanent delegation to the Conference on Disarmament based in Geneva."What is essential is to pursue practical and effective measures with the engagement of both Nuclear and non-nuclear weapon states", he said in remarks at the conference.
UN Secretary-General deputy spokesman Farhan Haq said that beginning of negotiations on a treaty to prohibit nuclear weapons is a vital initial step for global disarmament.
The corresponding resolution was supported by more than 100 countries, while Russian Federation and 35 other countries voted against it. "They did not sign (the cluster munition ban), but they know it's bad".
Meanwhile, major nuclear powers have rejected the initiative.
Countries not attending, like the United States and the United Kingdom, remain committed to the Non-Proliferation Treaty, which entered into force in 1970 and is aimed at preventing the spread of nuclear weapons and weapons technology. Fihn compares such arguments to the logic of chain smokers: "It's never the right time to quit".
