"Our foreign policy is also a class policy, because our Party follows a steady, persistent and honest peace policy which simultaneously stands unstakeably on the principles of proletarian internationalism and solidarity with the struggle of the peoples for freedom and social progress. There is no contradiction in this. We do not expect that the monopolistic bourgeoisie and the governments which are executing their will will endorse under the conditions of detente the revolutionary struggle of the proletariat or the national liberation struggle of the oppressed peoples. The Soviet Union does not put such demands on the West. But one should not demand of the Soviet Union to sacrifice its solidarity with those who are struggling against exploitation and colonial oppression."
