U.S. Ambassador Nikki Haley told reporters the countries skipping the negotiations are instead 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, according to Reuters.

"There is nothing I want more for my family than a world with no nuclear weapons. But we have to be realistic. Is there anyone that believes that North Korea would agree to a ban on nuclear weapons?" Haley told reporters.

The United Nations General Assembly adopted a resolution in December - 113 in favor to 35 against, with 13 abstentions - that decided to "negotiate a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination" and encouraged all member states to participate.

"In this day and time we can't honestly that say we can protect our people by allowing the bad actors to have them and those of us that are good, trying to keep peace and safety, not to have them."

Britain's U.N. Ambassador Matthew Rycroft said: "The UK is not attending the negotiations on a treaty to prohibit nuclear weapons because we do not believe that those negotiations will lead to effective progress on global nuclear disarmament."

Deputy French U.N, Ambassador Alexis Lamek said the security conditions were not right for a nuclear weapons ban treaty.
