Section A. Provision of basic necessities
In 1996, during a debate in the UN Commission on Human Rights, Mexico stated that internally displaced persons “must always be provided with the basic necessities”. It also stated:
The primary responsibility for dealing with the problem [of displaced persons] rested … with the State concerned, and that the international community should simply assist and intervene only in cases of massive and systematic violations of human rights.
