Activities of the Secretary-General: On March 21, 1950, the Secretary-General (Lie), in an address delivered at the triennial dinner of B'nai B'rith in Washington, D.C., called for a twenty-year program of peace within the framework of the United Nations. After referring to the difficulties arising from the non-participation of the Soviet Union in United Nations organs because of the presence of the representative of the Nationalist government of China, Mr. Lie suggested that negotiation between the major powers was possible if the Security Council would hold the “periodic meetings” referred to in Article 28(2) of the Charter, in which the various Members would be represented by either the heads of states or the foreign ministers.
