French nuclear testing in the Pacific was controversial in the 1980s, in 1985 French agents caused the Sinking of the Rainbow Warrior in Auckland to prevent it from arriving at the test site in Moruroa. In September 1995, France stirred up widespread protests by resuming nuclear testing at Fangataufa atoll after a three-year moratorium. The last test was on 27 January 1996. On 29 January 1996, France announced that it would accede to the Comprehensive Test Ban Treaty, and no longer test nuclear weapons.
