The Convention on Certain Conventional Weapons (CCWC) was concluded in 1980 as an “umbrella” treaty to which additional specific agreements might be attached in the form of protocols; at the time, three such protocols were concluded, dealing with: non-detectable fragments (Protocol I); mines and booby-traps (Protocol II and a technical annex); and incendiary weapons (protocol III). The Convention, of which the Secretary-General is the depositary, entered into force in 1983. It is kept under review in two contexts: wider adherence and broader scope, the latter either through the amendment of its existing protocols to make them more stringent or through the elaboration of additional protocols. By the end of 1995, the Convention had been ratified by 57 States.
