enterprise has a mining concession in Namibia; (b) The Government of Japan has called upon Japanese foreiqn exchange banks and f:heir branches abroad to refrain from extendinq any loans to South Africa. In the past year, as in previous years, Japanese banks have faithfully observed this appeal : (cl Thus, Japan confines its economic relations with South Africa to normal trade, and in this field it is to be noted that the Government of Japan does not in any way promote trade with South Africa. Rather, Japan has been making every possible effort to expand its economic relations with other African countries. Over the past 10 years, Japan has achieved a dramatic increase in its economic co-operation with the countries of Africa, and it is already the second-larqest non-regional subscriber to the African Development Bank and the second-largest subscriber of all the member countries to the African Development Fund. In the -2o- field of technical co-operation, over 40 per cent of Japan Overseas Co-operation Volunteer5 are sent to Africa where they promote co-operation at the grass-roots level. 4.

**Analysis**
The text primarily discusses Japan's economic relations with South Africa and its efforts to expand its economic cooperation with other African countries. It highlights Japan's commitment to the arms embargo against South Africa and its non-nuclear principles. The text does not touch on topics like natural resources, agriculture, or humanitarian aid. Given the focus on economic relations, international trade, and disarmament, I hypothesize that the text is most closely related to the categories of International trade, Economic development, and Science and technology.
