Premier Zhou and Chen Yi answer questions from reporters in Cairo. Zhou and Chen were asked about issues such as their visit to Arab and African countries, China's support for national liberation movements in Asia, Africa, and Latin America, the United Arab Republic (Egypt) and Sri Lanka's perspective of the Sino-Indian border conflict, the purpose of the Chinese delegation's visit to Arab and African countries, issues that will be discussed in potential second Bandung Conference, the Sino-Soviet split, and the Pakistani national movement. Zhou also explains why China opposed the ban on nuclear test treaty.

Zhou Enlai speaks with head of the Colombian House of Representatives delegation to China, José Ancizar Lopez, about an initiative to establish a nuclear weapons free zone in Latin America. Lopez agrees that nuclear weapons should not be used, but nuclear energy for medicine and other peaceful uses is good. Zhou calls on Latin America and Africa to take the initiative on preventing the use of nuclear weapons.

Zhou discusses China's relationships across the Middle East, including PRC policy toward Israel. He also reviews the proposed nuclear-weapons-free-zones in Africa and Latin America, as well as developments concerning the Non-Aligned Movement and the Second Asian-African Conference.

Zhou Enlai informs Mao Zedong that favorable weather conditions will allow them to carry out the aerial nuclear test explosion. An official statement for the press has also been prepared.

On May 10, Chinese military officials confirm that they are prepared to detonate an aerial nuclear explosion but, due to unfavorable weather conditions, must postpone the test until May 12 or 13.

Having successfully executed a nuclear test explosion, Zhou Enlai describes the Chinese government’s motivation for pursuing atomic weapons capabilities. Zhou argues that the Three-Nation Treaty (Limited Test Ban Treaty) is insufficient, that the United States remains committed to nuclear proliferation despite the agreement, and that China seeks to end the monopoly that other nuclear powers have thus far exploited. Zhou also calls for the organization of a global, truly equal summit at which to discuss the issue of nuclear weapons testing and proliferation.

Zhou Enlai notifies Mao Zedong and other prominent political and military officials that preparations have been made to detonate the explosion between October 15 and 20, depending on weather conditions. Attention is also given to the high level of secrecy surrounding the explosion, methods of data collection, publicity, and the political consequences of the explosion.

Zhou Enlai offers multiple dates on which the first nuclear test explosion may take place and asks Mao Zedong for his preference.

Zhou Enlai criticizes the Three-Nation Treaty (Limited Test Ban Treaty) of 1963, arguing that it signifies an attempt by the US, UK, and USSR to monopolize nuclear weapons. Enlai warns that the agreement will allow larger nuclear countries to commit “nuclear blackmail” against smaller, non-nuclear countries.

In the wake of a deepening Sino-Soviet split, Zhou Enlai explains how to manage Chinese bilateral technological and educational exchanges. Above all, Zhou emphasizes the importance of Chinese self-reliance in innovation and education as the country moves forward.
