Since the end of the Cold War, France has placed a high priority on arms control and non-proliferation. French Nuclear testing in the Pacific, and the sinking of the "Rainbow Warrior" strained French relations with its Allies, South Pacific states (namely New Zealand), and world opinion. France agreed to the Nuclear Non-Proliferation Treaty in 1992 and supported its indefinite extension in 1995. After conducting a controversial final series of six nuclear tests on Mururoa in the South Pacific, the French signed the Comprehensive Test Ban Treaty in 1996. Since then, France has implemented a moratorium on the production, export, and use of anti-personnel landmines and supports negotiations leading toward a universal ban. The French are key players in the adaptation of the Treaty on Conventional Armed Forces in Europe to the new strategic environment. France remains an active participant in: the major programs to restrict the transfer of technologies that could lead to the proliferation of weapons of mass destruction: the Nuclear Suppliers Group, the Australia Group (for chemical and biological weapons), and the Missile Technology Control Regime. France has also signed and ratified the Chemical Weapons Convention.
