We have met the engineers and technicians engaged in research here. We have seen with what enthusiasm new technology is being applied and the optimism with which the future is being viewed. All basic raw materials have been secured. Here you use not only lignite but also oil. This oil reaches you through the pipeline from the Soviet Union. You will also receive natural gas, and this will fully guarantee the raw material base for development of this plant. This leads to considerable technical and economic progress as well as security. Once upon a time the imperialist countries waged wars to secure their raw materials. Today, on the basis of the (?new) relations prevailing in the socialist community and on the basis of peaceful coexistence, these countries are developing, and this is how we obtain our raw materials. This is a conclusion of tremendous magnitude. Hence the great significance of socialist science and technology, since only from these countries, the socialist countries, can we engage in the necessary scientific and technical cooperation. We have an example in Cuba--the first small nitrogen factory for the manufacture of fertilizer. It was originally built by the capitalist. At the time of the victory of our revolution, the factory was not yet completed. It was not yet producing. The capitalist engineers left, and no one in Cuba knew the slightest thing about the manufacture of nitrogen. No one knew anything about the chemical industry. For several years our workers battled to put the factory into operation. And this was only possible when, much later and after great efforts, we received help from GDR engineers, that is when 25 technicians left for Cuba. Then after 3 years of hard work with these technicians, we finally managed to get the factory going so the manufacture of nitrogen could begin. Meanwhile, we have built a much bigger plant with a capacity of more than 400,000 tons of fertilizer. We already have 50 Cuban engineers and 200 technicians in the factory. At this very moment they are struggling to expand the factory. It we do not manage to overcome all difficulties we know we can rely on you. -END-
