UNITED NATIONS (AP) — Nations on Wednesday began signing the first treaty to ban nuclear weapons, a pact backed by over 100 countries but spurned by those with nuclear arms.
The U.N. treaty office said 51 countries are expected to attach their names on the opening day for signatures. Brazilian President Michel Temer was first to sign Wednesday.
The treaty requires all countries that eventually ratify it not to develop, test, produce, manufacture, otherwise acquire, possess or stockpile nuclear weapons “under any circumstances.”
“This treaty is an important milestone towards the universally held goal of a world free of nuclear weapons” at a time of increasing concern about their risk, U.N. Secretary-General Antonio Guterres said as he opened the signing ceremony.
It came alongside the annual U.N. General Assembly meeting of world leaders. Many were set to address the assembly later in the day, while the Security Council had scheduled a high-level meeting on its far-flung peacekeeping operations.
More than 120 countries approved the nuclear ban in early July over strong opposition from nuclear-armed countries and their allies, who boycotted the negotiations.
Supporters of the pact say it’s time to push harder toward eliminating atomic weapons than nations have done through the nearly 50-year-old Nuclear Non-Proliferation Treaty.
