The Mayor of Nagasaki expresses regret over China's second nuclear test.

This “Limited Distribution” report on possible Japanese reactions did not anticipate that a test would cause basic changes in US-Japan security relations or in Tokyo’s general approach to nuclear weapons.

This US analysis of the likelihood of nuclear proliferation during the next decade was finished only days after the first Chinese nuclear test on 16 October. The report analyses the implications of this test, as well as programs in India, Israel, Sweden, West Germany, Italy, Japan, Canada, and others. The National Intelligence Estimate (NIE) argued that India was the only new state likely to develop nuclear weapons, concluding that “there will not be a widespread proliferation …over the next decade.”

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.
