3. Nevertheless, there are scoe indications that Peiplng is continuing activities aimed at developing an etccic energy program of soase size. There is firm evidence of continued uranium Dining, and concoct rating activities. Recent official statements have reiterated that China lsetermined effort to develop nuclear weapons.

Such evidence as va have suggests that Congunist China's progress towarduclear weapons delivery capability with missiles has been vary slow since the general withdrawal of Soviet technicians in By that tine construction of the Shuangchengtzu Kisslle Test Range, begunad progressed to the point that Initial firings could have begun for purposes of checking out the missile facilities and range instrumentation, and for orientation of Chinese personnel. There is no reliable evidence which makes it possible toate at which actual flight-test firings for research and development might have begun, but va do not believe that these could have occurred much before the endl.

components of ballistic missile systems. Chinese research and

designs. This means that China'srogress t'jwurdallistic missile production capability entirely frou its ownis likely to be very slow.

12. Cur evidence ls insufficient to permit confJ ! estimates cn the timing of successive miasile developments. lor the present it seems unlikely tiat tho Chinese will receiverets tbe USSR. In developing their own production capability for offensive missiles, we believe they vould reck first to producesurface-to-surface ballistic missiles* In order to do so at an early date Polping would reed toicrlty effort to.aunecfcle the technical resourcesvculd_uicd to ac-iuirt* acme key ccepcoetts from external sources* If theseight bo abla to produce1ndlasllaa as early as lgfife. However, they would probably not deploy Such ndsoiles in any more than token numbers before they had anuclear warhead.

The areas falling within range of such weapons are shewn on tbe map at Annex.

The Chinese have ale est certainly not taken even preliminary steps to develop submarine missile systems, ICBHs, and antimissile systems. The achievement cf an independent capability in these more technically advanced fields would requireears or mere even with some Soviet assistance.*

Tie representative..of the Assistant Chief of Staff fcr Intelligence, Department of tbe Army, relieves that the limited Chinese Cooauniet Industrial base and relatively snail numbers of technicallypersonnel will prevent their production of any largo numbers cf ballistic missiles for the next few years. However, he believes this estimate does not give sufficient consideration to thecapabilities of the Communist Chinese es indicated by the facilities at tho Shuang-cbeng-tzu Missile Test Center. Be believes that tbe facilities at the Centerubstantial missile research and development program, rogram, If given sufficient priority and concentrated on eta or two missile systems of either short or medium range typo, could provide from nativeissile delivery capabilitymall number of compatible warheads when such warheads become available.

Aircraft ftoUvery Capabilities

15* Iccouse cf slew progress toward tbe acquisitionapability the Chinese Communists vould. If tbey succeeded In developing nuclear weapons In the next few years,to rely on manned aircraft for delivery of such weapons. The Chinese are now estlcated toet lightn and two BACOKRet medliijo boatoers. The light bibbers vould not be able to carry tbe crude weapons which are likely to be available In the early years of the Chinese program. The Chinese aircraft Industry is apparently United to tbe production of Soviet Jet fighters, small transports, and "cellccptoro, but not late models.

If the regime succeeds in overcoming the economic decline of recent years. It will probably devote larger resources to such programs. Because cf the generally low level of China's technology and the sas.ll cumber of trained personnel available, Chinese progress in such fields would ben any case.

The basic dependence cn nonnuclear military tactics and primary reliance cr. masses af troops will a. la estet .cue. However, the acquisition of advanced weapons would stimulate efforts to Improve military ergocitation and to develop new tactics andappropriate to nuclear war. It would probably also tord to improve tbe morale of tbe Chinese Armed Forces.

19. The Chinese would probably value nuclear weapons primarily for psychological support In exerting pressures short of general war. Even after acquisition of such weapons, we believe that the Chinese would prefer to advance their goal rf hegemony ln Asia by tba use of political pressures, limited border wars, and indirect support to local "wars of liberation."

22. Nuclear achievements might from time to tine lead Cancunist China to increase political pressures oa its nccaligned Asian neighbors but probably would not lead to any basic reorientation of policy toward tbea. Pelplng would probably seek, with sone success, to blur tbe distinction betweon an Initial test and full weapons capability in order to build tbe loage of full nuclear power status ^Dd scientific leadership. It would exert pressure cn neighboring states having nilitary re 1st ices with the US, ecphosizlcg tbe incrcated danger of nuch ties. These moves would probably be cautious, however, to avoid arousing fears er resentment arceg China's neighbors which night alienate or drive them toward the West, Propegarda would be likely to oaphasize China's peaceful Intentions and the defensive nature of its nuclear capability la contrast with "aggressive US designs" and military bases. The aim of such prcpegnada end pressure, would be tohinese Communist oriented neutralism among Asian states and especially among China's Immediate neighbors.

Toward the US end its Asian allies, Peiping would probably become acre aggressive vocally but It wculd still be concerned not

to provoke serious counteraction. It would realize that alc Itself was Insufficient to remove the CSAsia and, cn tbe contrary, might encourage the buildup ofmissiles in South Korea, Japan, and Taiwan.
