You are correct on the number. But the part about the Soviet Union, Im not so sure...

> History

Mao Zedong decided to begin a Chinese nuclear-weapons program during the First Taiwan Strait Crisis of 1954-1955 over the Quemoy and Matsu Islands. While he did not expect to be able to match the large American nuclear arsenal, Mao believed that even a few bombs would increase China's diplomatic credibility. Construction of uranium enrichment plants in Baotou and Lanzhou began in 1958, and a plutonium facility in Jiuquan and the Lop Nur nuclear test site by 1960. The Soviet Union provided assistance in the early Chinese program by sending advisers to help in the facilities devoted to fissile material production, and promised to provide a prototype bomb.[12] In July 1960, however, during the Sino-Soviet split, all Soviet assistance with the Chinese nuclear program was abruptly terminated and all Soviet technicians were withdrawn from the program.[13]

Whatever the original reasons for China's atomic bomb program, they became completely irrelevant after relations with the Soviet Union deteriorated.

By 1964, when the first Chinese atomic bomb was tested, China was barely on speaking terms with the Soviet Union. By 1969, China and the Soviet Union were on the brink of war. The Soviets tripled their forces in the Far East during the 1960s, deploying fully one-quarter of the Soviet military along the Chinese border. (They did this without drawing down their forces in Europe, which placed quite a strain on the Soviet economy.)

After Nixon visited China in 1972, Henry Kissinger even gave security briefings to Chinese generals, supplying them with satellite imagery and the location of Soviet forces.
