The Chinese have access, through the Joint Institute for Nuclear Beeearen. to the large Sovietat Dubna China's share of tbecosts of tbe institute Ishare exceeded only by that of the Soviet Union. We believe that the widespread Chineseand research effort Is coordinated to the needs of the military atomic energy program. Tbe Chinese Communists are now capable of comprehending and exploiting the large body of open scientific literature in tbe nuclear sciences. However, the present shortage of

trained scientist* and engineers will probably persist throughout the period of this estimate. This ihortage would hamper Chinese efforts to design, construct, and operate facilities for the production of fissionable materials and would be particularly serious, should thedecide lo reduce or terminate theiraid

nhe TMMB was renamed the Second Ministry of Machine Building. We do not believe that this change In name represented any real change In th* nature or functions of the former TMMB This belief Is supported by an announcement tn thepress on IB9 that Uo Chieh was Deputy Minister of tbe 8MMB. and on0 he was appointed minister.
