The Chinese Government endorses a proposal by the Soviet Union for the USSR, the US, and the UK to halt nuclear weapons tests.

Gromyko informs Liu Xiao of the Soviet position and strategy in its negotiations with the United States and the United Kingdom for halting nuclear tests.

Speaking at the Politburo, Zhou Enlai explains how nuclear weapons capabilities have won China newfound admiration in the non-aligned world and instilled fear in the other nuclear powers, particularly the United States and Soviet Union.

The Soviet Central Committee informs their Chinese counterparts that, in light of the arms reduction talks taking place in Geneva, Soviet nuclear assistance must cease. The Chinese had requested a sample atomic bomb and technical data, but the Soviet feared that doing so would imperil the efforts of the socialist countries in Geneva.

Khrushchev writes to Zhou outlining the Soviet Union's argument for the need to halt the testing of atomic weapons, and urges the Chinese to support and agree to the ban.
