text: and at Montreux, 1965_). The purposes of the Union as articulated in article 4 are: (a) to maintain and extend international co-operation between all members of the Union for the improvement and rational use of telecommunications of·all kinds, as well as to promote and to offer technical assistance to developing countries in the field of telecommunications; (b) to promote the development of technical facilities and their most efficient operation with a view to improving efficiency of telecommunication services, increasing their usefulness and making them, so far as posstble, generally available to the public; (c) to harmonize the actions of nations in the attainment of those ends. Co-operation in outer space is addressed specifically in article 33, "Rational Use.of the Radio Frequency Spectrum and of the Geostationary Satellite Orbit": 1. Members shall endeavour to limit the number of frequencies and the spectrum space used to the minimum essential to provide in a satisfactory manner the necessary services. To that end they shall endeavour to apply the latest technical advances as soon as possible. 2. In using frequency bands for space radio services members shall bear in mind that radio frequencies and the geostationary satellite orbit are limited natural resources and that they must be used efficiently and economically, in conformity with the provisions of the Radio Regulations, so that countries or groups of countries may have equitable access to both, taking into account the special needs of the developing countries and the geographical situation of particular countries. The work of the ITU is accomplished through the Plenipotentiary Conference, which is the supreme organ of the Union; Administrative Conferences, which formulate the Administrative Regulations (i.e., the Radio, Telegraph and Telephone Regulations); the Administrative Council, which acts to implement decisions of the Plenipotentiary Conference; and the permanent A/AC.105/C.2/16/Add.8 page 7 organs of the Union -the General Secretariat, the International Frequency 
analysis: The text appears to be discussing the International Telecommunication Union (ITU) and its purposes, which include promoting international cooperation and technical assistance in the field of telecommunications, as well as harmonizing actions to achieve these goals. The text also mentions the use of radio frequencies and the geostationary satellite orbit, which suggests a focus on the technical aspects of telecommunications. Given these themes, it is likely that the text falls under the category of "Transport and communication".
