SINO-SOVIET DISPUTE: New York, 18 – According to the diplomatic correspondent for The Associated Press, the most recent article by Soviet Foreign Minister Andrei Gromyko in the leading newspaper Pravda to mark the 10th anniversary of the Sino-Soviet mutual assistance pact signed in 1950 indicates that behind the expressions of friendship and solidarity between the two nations, their old rivalry has reared its head once more. Gromyko makes reference to what Russia has done for the Chinese Communists in the industrial sector by sending them machines and technicians, and emphasizes that in 1950 the two countries had assumed the responsibility of establishing peace and security throughout the world. He said the Soviet Union was ruled by four basic principles – respect for the sovereignty of other states, respect for their territorial integrity, nonintervention in the domestic affairs of other nations, and belief in equality and coexistence. China had not followed these principles – the most recent example being its invasion of India. The correspondent said it is clear by reading between the lines that there is deep disagreement between the two powers.
