TOKYO, Oct. 17, 1964 (UPI) -- Chairman Mao Tse-Tung maintains that Communist China has nothing to fear from nuclear weapons. But his people have paid a fearful price to develop the atomic bomb of their own. Mao is said to have told a Yugoslav visitor to Peking in 1957, "We have a very large territory and a big population. Atomic bombs could not kill all of us." "What if they killed 300 million of us? We would still have many people left." Advertisement Mao has never said such a thing publicly.
