"The ICRC is mandated by States through the Geneva Conventions and their Additional Protocols, and the statutes of the International Red Cross and Red Crescent Movement, to promote and act as guardian of international humanitarian law (IHL). This involves encouraging the ratification of treaties, monitoring compliance, dissemination and contributing to the development of IHL."
One of the purposes of the United Nations, as stated in its Charter, is "to achieve international co-operation in solving international problems of an economic, social, cultural, or humanitarian character."
