UN General Assembly
1965

12. It is our solemn duty to draw the attention of this Assembly to the grave and imminent danger of a unilateral declaration of independence by Ian Smith, and we appeal to all who cherish justice and human freedom to exert themselves to the utmost to discourage such a crime. My Government, for its own part, will not recognize such a minority government founded on rebellion. We shall vigorously oppose its admission to the United Nations, the Commonwealth and all other international organizations. We shall impose economic sanctions against it, we shall recognize an indigenous nationalist government in exile, and we shall take such other measures considered appropriate, after consultation with all other member States of the Organization of African Unity and all other States which respect justice and the essential dignity of man.
