Biological Weapon Convention (BWC) prohibiting the development, production and stockpiling of bioweapon was opened for signature in 1972. It was the first ever treaty completely banning the whole class of bioweapons. However, it lacked the mechanism for monitoring, implementation, and verification or compliance of the Convention provisions. State Pares held negotiations to correct this omission from 1995 to 2001 but the draft document wasn't approved. The difficulty was that the technology required for BW can be easily obtained and camouflaged by bioweapon producers and possessors. Many states are reported to have or are seeking an offensive bioweapon capability. China, Iran, Iraq, Israel, Libya, North Korea, Russia, Syria, and the USA are some of those which are often mentioned in this regard. While some others such as Cuba, Egypt, India, and South Korea have also acquired this capability. Besides, there is an increasing concern in the world now about the ability of non-state actors to employ bioterrorism.
