States that do not have nuclear weapons, which include most developing countries, have an opportunity to demand greater access to nuclear sciences and technologies for peaceful purposes, including for energy, industry and medicine, at the tenth review conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), scheduled for August, Ambassador of Norway to Southern Africa Stian Nordengen Christensen has pointed out. Non-nuclear weapon armed States, and African States in particular, aim to focus on peaceful uses of nuclear energy at the upcoming review conference and they have the full support of Norway, he said during a discussion hosted by the South African Institute of International Affairs on May 13.
