Malaysia has become the 46th nation to ratify the Treaty on the Prohibition of Nuclear Weapons. Its minister of foreign affairs, Hishammuddin Hussein, signed the instrument of ratification for the landmark disarmament treaty at a ceremony in the nation’s capital, Kuala Lumpur, on 30 September 2020. It was deposited with the United Nations later that day. Just four more ratifications are now needed to bring the treaty into force.
