Since 1999, the GICHD has supported the implementation of the Convention, primarily by hosting meetings of the Standing Committees established by the Convention’s States Parties. In September 2001, the States Parties mandated the GICHD to provide enhanced support to their efforts through the establishment of an Implementation Support Unit (ISU). The ISU's duties include providing support and advice to the Presidency of the Meetings of the State Parties and to Standing Committee Co-chairs, communicating information about the Convention and its implementation, and developing and maintaining a Documentation Centre.
