ABSTRACT
The importance and excellence of Sino-Soviet relations received striking confirmation on two occasions during 1950: once when Mao Tse-tung visited Moscow, followed by the signing of the treaty of February 14, 1950, and during the Korean War. The Korean War, which was to break out a few months later, altered the nature of Sino-Soviet economic cooperation from the outset because priority had to be given to military aspects. The North Korean invasion of June 25,1950, first led to the occupation of Seoul after only a few days; this was countered partly by the creation, in July, of an American bridgehead in the Pusan area, and partly by a powerful landing at Inchon on the principal North Korean lines of communication. In so far as China had sooner or later to accept the modern doctrine of the need for international cooperation, the Korean War appears as an unfortunate mistake in itself and for the world community.
