Comrade N. S. Khrushchev, First Secretary of the Central Committee of the Communist Party of the Soviet Union and Chairman of the Council of Ministers of the USSR,
Comrade L. I. Brezhnev, Chairman of the Presidium of the Supreme Soviet of the USSR:

The Soviet Union has successfully launched in succession the manned satellite spaceships "Vostok-3" and "Vostok-4," achieved a joint formation flight in outer space, and smoothly returned the spaceships to Earth. This is a new and major victory for the Soviet people in the conquest of outer space. The Chinese people feel immensely elated over this. We hereby, on behalf of the Chinese people, the Chinese Communist Party, and the Chinese Government, and in our own names, extend the warmest congratulations to you, and through you to the Soviet people, the Soviet Communist Party, and the Soviet Government, as well as to the cosmonauts Major Nikolayev and Lieutenant Colonel Popovich who piloted the spaceships.

This new victory of the Soviet people is another great contribution to mankind’s conquest of outer space. It once again demonstrates the powerful might of the socialist camp and the incomparable superiority of the socialist system, and greatly inspires the people of all socialist countries and the people of the whole world in their struggle against U.S. imperialism’s policies of aggression and war and for the defense of world peace.
