text: quoted it was natural for a great Power to tell tbe Security Council that it had decided to continue to buy chromium, despite the ban, because it could not find it cheaper elsewhere. Another quotation: &slce in Erh&!.bhl "He pointed out the United States imports of strategic material8 from Southern Rhodesia amounted to only 2 per cent of the Territory's total exports of those commodities*', t-in It was in 1972 tbat the then Bermanent Flepresentative of the United States told that to the Security Council.

analysis: The text appears to be discussing the importation of strategic materials, specifically chromium, by the United States from Southern Rhodesia, despite a ban by the United Nations Security Council. The text also mentions the arms embargo against South Africa and the United States' continued supply of spare parts under pre-existing contracts. These topics suggest that the text is related to international trade, economic development, and international relations.
