中国研制原子弹的工程叫“596工程”。这与中苏两国的关系密切相连。随着中苏分歧的扩大,1959年6月,苏联决定,提前中止关于国防新技术的协定,中断若干援助项目,不再向中国提供原子弹模型和生产原子弹的技术资料。这对当时的中国来说,无疑是一个很大的打击。中国马上在1959年7 月做出决定,自己动手,从头摸起,准 China’s project to develop atomic bombs is called “596 Project.” This is closely linked to the Sino-Soviet relations. With the expansion of Sino-Soviet differences, in June 1959, the Soviet Union decided to prematurely suspend the agreement on new technologies for national defense, interrupt several aid projects, and no longer provide China with atomic bomb models and technical materials for the production of atomic bombs. This was undoubtedly a big blow to China at the time. China immediately decided in July 1959 that it should start from scratch and start from scratch.
