生物兵器禁止条約
The Soviet Union ratified the Geneva Protocol—prohibiting the use of biological and chemical weapons—on April 5, 1928 with reservations that were later dropped on January 18, 2001. Russia is also party to the 1972 Biological Weapons Convention and the 1993 Chemical Weapons Convention. The Soviet biological weapons program violated the Biological Weapons Convention and was the world's largest, longest, and most sophisticated program of its kind. At its peak, the program employed up to 65,000 people. In 1997, Russia declared an arsenal of 39,967 tons of chemical weapons.
