The United Nations is observing the International Week of Solidarity with the Peoples of Non-Self-Governing Territories from May 25 to 31, 2021. On December 06, 1999, the UN General Assembly called for the annual observance of the Week of Solidarity with the Peoples of Non-Self-Governing Territories. In UN Charter, a Non-Self-Governing Territory is defined as a Territory “whose people have not yet attained a full measure of self-government.”
The observation aims to take effective measures to safeguard and guarantee the inalienable rights of the peoples of the Non-Self-Governing Territories to their natural resources, including land, and to establish and maintain control over the future development of those resources and requested the Administering Powers to take all necessary steps to protect the property rights of the peoples of those Territories. At present, there are 17 Non-Self-Governing Territories remaining.
