The 21st session of the Contracting Parties to the General Agreement on Tariffs and Trade (GATT) was held in Geneva from February 24 to March 20, 1964, under the chairmanship of Mr. J. H. Warren, Assistant Deputy Minister, Department of Trade and Commerce, Canada. Much of the work of the session was concentrated upon the trade problems of the less developed countries.

The Council of the Intergovernmental Committee for European Migration (ICEM) held its twentieth session on October 14–18, 1963, under the chairmanship of Mr. D. Ramon Huidobro, permanent Chilean representative to the European Office of the UN. ICEM Director B. W. Haveman keynoted a discussion of ICEM's proper role with his request that fuller use be made of ICEM's migration machinery which, he pointed out, had aided in the resettlement of some one and one-quarter million people during the past eleven years. Mr. Haveman's proposals for future action included: 1) making the good offices and machinery of ICEM available in areas in which ICEM did not at present operate; 2) establishing improved reception and placement services, especially in Latin America; 3) exploring the possibilities of making the fullest use of ICEM in carrying out governmental migration policies and programs; and 4) encouraging the settlement of European farmers in Latin America.
