During September and October 1958 the Permanent Council of the North Atlantic Treaty Organization (NATO) discussed the question of Cyprus. On September 24, the Council heard M. Paul-Henri Spaak, Secretary-General of NATO, describe his visit on September 23 to Athens, where he had discussed problems connected with Cyprus with the Greek Prime Minister. His consultation had centered on a United Kingdom plan whereby there would be a seven-year partnership in Cyprus to provide a quiet atmosphere and proper conditions under which to work out a final solution; the plan had received the support of the Turks but not of the Greeks. M. Spaak proposed to the Council the calling of a conference in which the Greek, Turkish, and United Kingdom governments and representatives of the Greek Cypriot and Tyrkish Cypriot communities would take part.

On January 13, 1958, a special committee which had been created to draw up the general policy to be followed in carrying out a proposed fellowship program of the Organization of American States (OAS), in addition to the regular fellowships already offered by the organization and the individual governments, presented a report and draft resolution to the Council for consideration. In accordance with the temporary provision of a resolution on the general policy for the fellowship program approved by the Council of OAS on January 15, Secretary-General Mora prepared the regulations for the award and administration of the fellowships and presented them to the Council at a meeting held on June 4, 1958. At that time it was agreed that the representatives on the Council would forward the regulations to their governments and that they would also be transmitted to the Committee on the Fellowship Program for its information. The regulations stated that the Secretary-General of OAS should be assisted in the administration of the program by the Executive Director of Technical Cooperation, the Technical Secretary, and an Advisory Board. According to the regulations, an OAS fellowship was one to be granted by the organization, after consideration of the applicant's study plans, to a person with advanced training in the branch of knowledge in which he had specialized, so that he might have an opportunity to study abroad. The regulations included sections on the selection of candidates and the processing of applications, and forfeiture, renunciation, and cancellation of fellowships.

The eighteenth session of the South Pacific Commission was held at Commission headquarters in Noumea, New Caledonia, from September 26 to October 12, 1958. At the session the Commission placed emphasis on the need for an all-out campaign against the rhinoceros beetle, which had become a major threat to the economy of the South Pacific. The Commission decided that a meeting of its rhinoceros beetle advisory committee of leading Pacific entomologists would be held in Suva from February 16 to 20, 1959, to review results of present campaigns against the beetle, and to plan further action. The Commission also made a further grant of £3,000 for 1959 to assist the investigation being carried out on its behalf by the Institute of Scientific Research in Madagascar.

The fifth meeting of the Southeast Asia Treaty Organization (SEATO) Council was held in Wellington from April 8 to 10, 1959, under the chairmanship of the New Zealand Prime Minister and Minister of External Affairs, the Right Hon. Walter Nash. The Council discussed reports and recommendations by the Council representatives, the military advisers, and the Secretary-General, and in the light of them gave directions with regard to the activities of the organization in the coming year. The communique issued at the close of the meeting noted that despite the continuing possibility of open aggression, the principal threat to the security and independence of the treaty area was now being presented in more indirect forms. The Council members were aware of the opportunities afforded for subversive activities in situations where basic problems of hunger, lack of opportunity, and underdevelopment remained unsolved. The Council stated that SEATO had done much to publicize and expose throughout the treaty area the objectives toward which subversion was directed and the methods by which it operated, and it agreed that during the coming year arrangements should be made for the further strengthening of this aspect of SEATO's work. For example, it was proposed that a meeting of experts on counter-subversion should be held in Pakistan. The Council members recognized the need for continuing action in the economic and social spheres.

The Assembly of Western European Union (WEU) held the second part of its fourth session in Paris from December 17 to 20, 1958, under the presidency of Sir James Hutchison (British Conservative). In the course of the session, the Assembly was addressed by the Foreign Ministers of Belgium, the German Federal Republic, and the Netherlands, by the United Kingdom Under-Secretary for Foreign Affairs, by the Secretary-General of the North Atlantic Treaty Organization (M. Spaak), and by the Supreme Allied Commander, Europe (General Norstad). The Supreme Commander considered that if a demilitarized zone was established in Europe, as suggested in the Rapacki Plan, his task would become impossible; M. Spaak also had little faith in a denuclearized zone, in an era of intercontinental missiles.

The tenth annual meeting of the Consultative Committee of the Colombo Plan for Cooperative Economic Development in South and Southeast Asia was held in Seattle, Washington, November 10–13, 1958. At the meeting the committee's seventh annual report was adopted. It was reported that President Eisenhower, who attended the conference, outlined a five point plan for economic growth which called for expanded international trade; more technical assistance; more private investment; public loans on normal bankable terms; and development financing to provide to the borrower flexibility regarding terms of repayment. Mr. Eisenhower observed that the Development Loan Fund established in 1957 by the United States Congress had given more than half its loans to the Colombo Plan countries. Additions to the fund were needed since Colombo Plan nations had requested further loans for projects which exceeded the resources of the fund. He suggested that progress would be hastened if other more developed countries were to act to meet these growing needs and said that the United States would welcome the contributions of other countries to this end. He spoke of the possibility of creating an international development association for this purpose, as an affiliate of the International Bank for Reconstruction and Development. During the committee's session, it was pointed out by some participants that less developed countries should prepare a satisfactory climate, with investment safeguards, if large private investments were to be expected. Several representatives from less developed areas concurred in this position, referring to steps already taken in this direction. It was decided to hold the next annual meeting of the committee in Indonesia.

The ninth session of the Council of the Intergovernmental Committee for European Migration (ICEM) met in Geneva, November 13–19, 1958. At the opening meeting of the Council the government of Panama was welcomed as the 28th member of ICEM. On November 14, the Council approved two pilot projects for developing services to assist migrants and the governments of emigration and immigration countries. One was the establishment of an international vocational training center at Cattolica vocational training center at Cattolica in Italy to train workers for emigration to overseas immigration countries, as well as for intra-European emigration. The second project was the organization of a training course for immigration and placement officers to be set up by migration officials of the Canadian government; the task of this course was to give theoretical and practical training to officials of various immigration countries to fit them for selection, counselling, and placement of immigrants. At the same meeting, the Council decided to make fresh appeals for further financial contributions from its member governments to pay for transport of European refugees from the Far East to countries of asylum.

In a communique issued by the Inter-national Tin Council on January 27, 1959, it was announced that the Soviet Union had agreed to limit its tin exports outside the socialist countries to 13,500 tons in 1959, a reduction over the exports in 1958. According to the press, the Council had been in conflict with the Soviet Union over the amount of the latter's exports in 1958, which were believed to have been 18,000 tons. As stated in the communique, the result of the negotiations between the Council and the Soviet Union was no more than an understanding.
