However natural it may seem, a world agreement on proteins has encountered many difficulties owing to the different policies of those concerned. The U.S. wants to dominate the consumer market by measures that encourage exports (P.L 480 Food Aid for Peace, General Sale Manager) and also by the efforts of professional organizations such as the A.S.A. and multinational firms. The U.S.S.R. would like to play an international market that is anarchic enabling it to intervene from time to time within its own policy (the sale of sunflower-seed oil in spite of the poor harvest and the purchase of cheap American soya oil). Europe would like to retain a little ot if s indépendance and to play on the price fluctuations but without being equipped to practise this policy because of the diversity of the economic motivations of the member states. In these agreements the developing countries would like to see results that their possible partners consider excessive. In this situation it seems difficult to establish a world agreement in the near future, but this economic system was shaken by a serious crisis in 1973 which might well occur again and result in an international agreement.
