Minutes from a meeting on Sino-Soviet efforts at defense planning and collaboration. Chinese defense officials looked for Russian help in the production of guided missiles, and the document illustrate their efforts to collaborate in the education and preparation of specialists, the staffing of military research institutes, the construction of defense-related factories, and the sharing of technology.

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.

In a conversation with Soviet ambassador Yudin, Mao sees a prohibition of the use of hydrogen weapons as very likely, as the capitalist countries "[fear] fighting this kind of war." Further, he notes that the socialist countries have an advantage over Western ones in terms of conventional army size.
