To examine the current status and effectiveness of controls on trade withChina.

To examine the short and long term effects on the capabilities of the Chinese Communist regime of:omplete embargo;aval blockade, alone orwith bombardment of transportation facilities in Communist China; andhinese Nationalist effort at blockade and aerial bombardment.

To estimate Communist reactions to these measures.

This estimate does not consider whether the UN would cooperate in theseor what the reaction of other non-Communist powers would be li the US adopted these measures unilaterally.

This estimate does not consider the probable consequences of substantiallyUS or US/UN military operations in Korea or Ctommunist Chinain conjunction with some or all of these courses of action.

This estimate assumeslockade of Communist China would not involve interference with shipping to ports of the Soviet Far East.


controls on trade withChina have not prevented the build-up of Chinese Communist military strength. Moreover, Communist China's industrial and internal transportation systems have continued to expandutreater cost to the Soviet Bloc andower rate than if Western controls had not been in effect.

A total embargo on non-Communist trade with Communist China would prob-

ably have no significant effect on Chinese Communist capabilities to sustainoperations in Korea or to undertake military operations elsewhere, but would retard the expansion of Ciiineseindustry. An embargo would make Communist China economically moreon the USSR. An embargo would probably not induce the Communists to embark on new aggression, but would probably lead them to intensify political warfare.

aval blockade of Communist China1 would increase tlie difficulty of Chinese Communist military operations requiring large expenditures of materiel, either in Korea or elsewhere. The presentmaximum capacity of thc inland transportation facilities servingChina is probably adequate to carry essential tonnage now seaborne plus the essential traffic now carried bylockade would create serious economic problems. For instance,do not serve all parts of Communist China now served by coastallockade would make Communist China economically more dependent on the USSR and would retard theof Chinese Communist industryreater extent than an embargo. Wethat thc political controls within Communist China are now so strong that their effectiveness would not beby these economic difficulties.

n reactionaval blockade, the Chinese Communists would almostattack thc blockading forces, with covert Soviet assistance, and might launch new acts of aggression, such as the seizure of Hong Kong and Macau. The USSR might reactavalby attempting to bring merchant ships into Port Arthur and Dairen under Soviet naval escort, by attempting to force the blockade at other points, or by waging mine and submarine warfare

Large scale and sustained air and naval bombardment of key Chinesetransportation lines,aval blockade, could sharply reduce Chinese Communist niilitaryCommunist China's economic potential would be seriously affected, and the physical problems of the regime in maintaining control would be increased-

In reactionlockade andthe Chinese Communists wouldaximum air defense effort in China and Manchuria. Units of theAir Force in Uie Far East would covertly participate in the air defenseparticularly in Manchuria. The Chinese Communists would probably also employ their air capability against some US/UN bases in the Far East. We believelockade und bombardment would not in itself induce thc Communists toorean settlement on UN terms.

In the unlikely event that the blockade and bombardment should threaten the existence of thc Chinese Communistthe USSR would increase its ajd to Communist China, possibly even to the point of openly committing Soviet forces against US forces in US/UN heldand adjacent waters in the Far East.

Blockade and bombardment by the Chinese Nationalists alone would notpresent conditions of Chinesestrength and operational efficiency,ajor effect. In reaction to a

Chinese Nationalist blockade andthe Chinese Communists would almost certainly attack the block-

ading and bombarding forces and might retaliate by air against Nationalist-held territory.*



ost of the naUons outside the Soviet Bloc apply some form of export controls over trade with Communist China. The US hasa total trade and shipping embargo against Communist China, as well as controls over the dollar assets of Communist China, sinceanada, Japan,China, and the Philippines havetrade restrictions almost as severe, while Costa Rica, Honduras, Liberia, and Panama have imposed strict controls over thc movement of their vessels to Communist China.

n East-West trade applied to Communist China the selective controls earlier put into effect against the rest of the Soviet Bloc. After Communist China was declared an aggressor by the UN, theseInstituted controls over trade withChina more severe than the controls over trade with the rest of the Bloc. At thc present time, tlie COCOM countries embargo to Communist China all Items Included on the three International Lists plus somedditional items of particular strategicto Communist China.hina Committee (CHINCOM) parallel to COCOM was set up in the fall2 for the purpose of working out international export controls to be applied in the Far Eastreatof other nations have also taken action to restrict strategic shipments to Communist China in accordance with the UN AddiUonal Measures ResoluUon of TheAct, enacted In the fallas served to reinforce the COCOM and UN embargo by making the continuation of US assistance condiUonal upon the recipient country'sin supplying controls over strategic shipments to tho Soviet Bloc, includingChina.

here haside variation, however, in thc contraband lists and enforcement measures used by individual countries.the controls imposed by the UK and thc continental COCOM countries are fairly comprehensive, they fall short of the total embargo imposed by the US. Other nations, which are largely non-industrialized and do not produce strategic equipment, have shown little uniformity in their interpretation of the UN Resolution, which covers transportation

Ceylon, which Isember of the UN, has refused to comply with the UN Resolution so far as shipments of rubber to Communist China are concerned.

hipping controls have been particularly weak. Thc COCOM countries prohibit the sale of ships to Communist China and Impose restrictions on the sate of merchant ships to the rest of thc Bloc. Since0 at leastessels have been transferred toBloc flags. However. COCOM restrictions on sales were tightened somewhat The US alone has imposedformal controls on ship sales,and bunkering. During thc past year,loc ships,rosstonnage, receivedays or more of repair work each in Western shipyards. Only the US, Costa Rica, Honduras, and Panama prohibit vessels of their registry fromChinese ports, although Liberia prohibits vessels of Its registry from carrying strategic cargo to Communist China. Present COCOMcontrols do not prohibit the chartering of} merchant vessels other lhan tankers lo the1 Soviet Bloc and this prohibition has not beeneffective. Although the greater percentage by far of chartered vessels do not touchCommunist ports, these vessels are used by the Soviet Bloc In Western European, South AUanlic and Indian Ocean trade and make possible the release of Communist flag vessels for direct service to Communist China.

It Is believed that the Chinese Communists arc attempting to Increase these exports still furtherpparently In an effort to reduce Uie trade deficit with the Soviet Bloc. Seaborne exports to thc Bloc2 are estimated roughlyons andconsisted largely of grain, soy beans, and ores. On the basis of partial evidence, wc estimate the volume of overland exports to thc Soviet Bloc2 at three million tons.

Over-All Effects. Present trade controls appear to have been an Important factor in the sharp change Uiat has occurred InChinas foreign trade.nly one-fourth of Communist Chinese foreign trade was with thc Soviet Bloc while three-fourths was with thc West;hese proportions were almost reversed. However, other factors would have tended to increase Soviet Bloc exports to Communist China even if Western trade controls had not existed These factors are: (a) movement of Soviet military supplies in support of thewar effort in Korea; (b) shipment of non-military items to Communist China inof Soviet commitments in the Sino-Soviet agreements0 to provide economic assistance; and (c) the avowed policy of thc Communist Bloc to achieve economic self-sufficiency.


Effects. The restrictionInto Communist China as apresent controls has not curtailedoutput. In fact, because of thelevel of commercial importsSoviet Bloc and thc more effective useequipment and stocks inChina, Industrial output has continued

Io expand. However, this expansion would probably have been greater if the present trade controls were not ln effect.

Effect on the Railroads. The railroad transportation system of Communist China, while not expanding to the extent it would have without present Western controls, has steadily improved in capacity andControl measures have stoppedfrom thc West of locomotives, freight cars, parts for rolling stock, and rails.the Soviet Bloc has supplied limited quantities of these items which, together with local production, has permitted theof existing equipment and continued expansion of the rail network, despite the losses in Korea.

Effect on Other Internal Transportation. The expansion of molor freighthich has occurred in Communistas been made possible largely by Imports of Soviet trucks and petroleum. However, thc traffic in smuggling of parts for motor vehicles continues to be considerable, Indicaling that Soviet Bloc assistance has not kept pace with expanding Chineserequirements and that Western controls are imposing some cost on Communist China ln this regard. Coastal shipping has not been appreciably affected by Westernsince most non-Communlst countries permit their flag vessels to operate in the Chinese Communist coastal trade.during the last year thc Chinesedemand for foreign coastal shipping seems to have slackened, and it ls possible that an Increasing part of Chineserequirements for river and coastalcapacity is being met by their own fleet.

Over-All Eccmomicespite the curtailment of trade with the West, during the last two years thc Chinese Communist regime has made rapid progress In economic reconstruction, particularly in theand expansion of its Industrial capacity. However, the reduction In Communist China's net receipts from foreign trade must be viewededuction from the resources thatwould have been available to the gov-

ernment for Investment Without Western trade restrictions, Communist China'sprogress probably would have been greater than lt actually was. and lt certainly could have been accomplished at less cost to the Soviet Bloc.


Ground Forces. Although Western trade controls have made it difficult for theto acquire certain Important items such as antibiotics and other medicalcommunications equipment, andproducts, the Chinese Communist ground forces have not been adversely affected by Weslern trade controls. Communist China producesart of Its own light ground force equipment and supplies. Therequired for Communist China'sindustry are relatively small in tonnage and are for thc most part producedThc only important importarc for copper and sine, which arein adequate quantities for the most essential uses by the USSH. In addition, thc USSR is providing most of thc heavy military equipment, virtually all POL,arge share of thc light equipment and supplies used in Korea.

Air Force. Since the USSR provides Communist China with virtually all aviation equipment and supplies Including avgas and Jet fuel, present Western controls on stralegic materials have not affected the capabilities of tbe Chinese Communist Air Force. The Air Force has continued to expand in aircraft strength and capabilities throughout thc period of present Western controls.

Navy.arge part of the Chinese Communist Navy is composed of formernaval vessels, present Western controls on strategic materials have almost certainly hindered thc Chinese Communists in their efforts to put back into service and maintain their naval vessels. As far as is known, the USSR has supplied at mostew small warships to the Chinese Communists, forcing them to rely almost entirely on those ships taken over from the Nationalists.

INTERNAL POLITICALestern trade restrictions have notaffected the Chinese Communist regime's ability to consolidate its political position. In fact, the restrictions have been cited by the Communists Ln domesticas an additional Indication of thehostility of the West, and thus have provided the Chinese Communists with afor applying further stringent political controls.


ntroductory Note. The impositionotat embargo by the entire non-Communist world would presumably extend to both trade and shipping. The Implementation of such an embargo would presumably includeto prevent the transfer or charter of non-Communist shipping for the Communist China trade, the denial of bunkering,and repair in non-Communist ports of ships bound for and returning from Chinese Communist ports, and the transshipment of non-Communlst goods directly or indirectly to Communist China from other countries Ln the Soviet Bloc. The following factors would prevent effective enforcementomplete embargo:

a Although transshipment mightimited extent by placingcontrols on goods exported from the West lo Eastern Europe and the USSH.prevention of transshipment would be impossible so long as trade controls applied against these countries arc less rigid than those applied against Communist China. Such transshipment could only be stopped completely and Communist China denied all non-Corrununlst commodities If trade with the entire Bloc were embargoed.

b. As indicated above, several countries are not now cooperating with the limited embargo declared by the UN. and most Westernarc now strongly opposed to further ex-

tension of trade and shipping controls against thc Soviet Bloc and Communist China. Even should the UNull embargo on trade with Communist China, ll Is probable that various Asian and Middle Easternwould not cooperate because of theiroreign policies and thc economic importance of trade with Communist China.


Effect on Trade. Thc direct Impact on Importsotal embargo would depend on the extent to which the Soviet Bloc was able and willing to: (a) make up for the loss of Western shipping (including that nowby the Communists) now serving the China trade; and (b) supply the specific commodities denied by thc West

In view of the incomplete data on Communist China's foreign trade and on thc Soviet Bloc's capabilities, it Is Impossible to estimate with precision the impactotal embargo on Communist China. The following projection is based on thc estimated level of trade

hc Soviet Bloc could assume the entire burden imposed by an embargo and supply to Communist China all of the commodiUcs it otherwise would have received from Uie West Such commodities are available in Uie Bloc and transport facilities would not impose an absolute limit on then* shipment. However, the degree to wluch the Soviet Bloc would compensate for Uie loss of imports from Uie West would depend in general on the Soviet appraisal of thc relative advantages of using these resources In Communist China asto using Uiem elsewhere in the Soviet Bloc. Including the USSR itself.

a. The Soviet Uniontrong interest in maintaining Chinese Communist strength and for this reason would probablyigh priority to those Chinese Communist import requirements trialignificant effect on Chinese Communist militaryMuch lower priorities would beto supplying Uie remaining cominodi-ties Communist China formerly imported from the West. It is probable, therefore, that such commodities would be supplied only to the degree that Uie burden thus imposed on Uie rest of thc Soviet Orbit would be relatively small. On the basis ot these considerations.

It Is roughly estimated that the Bloc would supply virtually all the iron and steel,and metals, and drugs; most of Uie heavy industrial chemicals, dyes, and paper; and only part of the crude rubber, chemical fertilizer, and other miscellaneousThe Soviet Bloc would probably not compensate for any of the raw cotton, gunny bags, and some miscellaneous .commodities. Wc esUmate, therefore, that in making up thc imports lost through Imposition of an embargo, the Soviet Bloc would probablyIts annual exports to Communist China byons valued0 million, reducing the net Import loss toons.

b. If these additional Imports from the Bloc were carried by sea, total seabornefrom the Bloc In Bloc vessels would amount toons

This wouldeduction of approximatelyercent in the value ofChina's total imports and perhaps as much asercent of non-military Imports. It is evident, therefore, that impositionomplete embargo on Western imports would notajor reduction In the present total volume of imports. Communist China's total exports would be reduced by SIillion, or by more thanercent. The proportionate reduction in thc volume of ex-ports would be greater.

otal embargo on non-Communlst trade witb Communist China would not affect Uie flow of purely military Items and petroleum, all of which (except for limited quantities brought in by smuggling) now come from the Soviet Bloc. Military considerations would almost certainly determine the reiaUveof compensating shipments from the Soviet Bloc and, conscquenUy, goods related to miliiary opcraUons would probably be least affectedomplete embargo.

conomic Effects. The Chineseeconomy has already made considerable progress in adjusting to decreasedof western goods. The main effccl on Uie Chinese Communist economy of aembargo would be, therefore, to force more rapid adjustmentsattern already being developed. Although the reduction in imports resulting from thc embargo probably would retard Uie planned expansion ofCommunist industry, principally with regard to planned increases in theof consumers' goods, these losses inwould Ln part be offset by Uie increased availability for domestic consumption of some

commodities that formerly were exported to Uie Wesl. The loss of foreign Sag shipping for domesUc coastal services would reduce coastal shipping capacity. However, Communist shipping, which now carries the bulk of this trade, and the North-South rail lines could absorb the load now. handled by foreign flag ships.1* Finally, with imports and producUon of some consumer goodsand non-Communist markets virtually eliminated, tho government wouldizable loss of revenue. These losses, however, would be minor In relation to Uie total naUonal income and to totalCommunist budgetary expenditures.

Chineseplans for tlie continued expansion of heavy industry would not be appreciablysince such plans even now arealmost wholly on imports of capita] goods from the Soviet Bloc and on Increasedproduction of capital goods. However, greater emphasis probably would be placed on thc expansion of rail transport links with the Soviet Union at aome expense to other aspects of thc development program. Finally, ln view of current estimates of the rates of growth of thc gross national products of the USSR nnd European Satellites, the ability of the Soviet Bloc to provide capital goods and to bear the costs of providing such goods will increase significantly over theears.

The capacity and efficiency of the Chinese Communist railway system have apparently Improved to the point where it could handle any additional burden which mightotal embargo. Tlie plannedof Chinese Communist railway lines and Uie possible Increased load underof an embargo would require additional equipment and supplies. This would place some burden on Uie Soviet Bloc, whether it sought to supply Uie necessary rails,and freight cars Itself, or attempted to restore Manchurtan capacity for rolling stock and steel rails and to expand Uie production of freight cars and locomotives in China. However, It Is probable that Uie Soviet Bloc would be able to supply minimum Chinese Communist requirements without serious repercussions in other portions of Uie Soviet Bloc economy.

aval blockade would cut off Chinese Communist total seaborne imports, which amount4 million tons per year. The amount by which Communist China's total imports would be reduced thereby wouldprimarily on the extent to which tlie Soviet Bloc increased its present level ofto Communist China. Secondarily, thc amount by which total imports were reduced would depend on the capacities of the Trans-Siberian railway and of Communist China's inland transportation facilities.

Communist China wouldbe able to* increase its exports lo the Soviet Bloc sufficiently to avoid any significant increase Ln its trade deficit with the Bloc.

In this event, however, the cost to tlie Soviet Bloc ofthese commodities would be substantially increased. Thc movement of this tonnage could be accomplished by:iversion of additional rolling stock from other rail lines in the Soviet Union;eduction in Lhc peacetime volume of commodities moving to the Soviet Far East; and/or (c) movement oi freight by sea to Vladivostok to be on-carried lo connecting Manchurian railways.

It is estimated thatof the long average haul involved, the transportation overland of the freight cut oillockade would require aboutercent of the freight car park andercent of the locomotive park. We believe the Chinese Communist railroads have'the capacity to carry this additional freight, but it should be noted that some parts of mainland China now served by coastal shipping arc not served by rail lines.

Since the additional burden of essential tonnage placed on both the Trans-Siberian Railroad and the internal transportation sys-lein of Communist China could probably be


carried with existing cupacity, we believe that the reliance on overland transportationwould not limit the extent to whichChina's essential seaborne imports could be replaced. Moreover, it should be pointed out that it would be possible for the USSR to ship goods to China by sea toand thence by rail to China.11

conomic Effects. A naval blockade wouldreater effect on the Chinese Communist economy than would an embargo. The planned economic growth would beretarded, additional strains would be placed on internal transport, and further gains from trade and further budgetarywould be lost- In those areas which arc now served by coastal shipping and which arc not served by rait lines, particularly Southeversion to moreeans of transport would result. Thcin Imports of fertilizer and Industrial chemicals would adversely affect plans tooutput of industrial crops and sonic

"The Director of Naval Intelligence and theDirector for Intelligence. Tbe Joint Starr, believe that paragraphsi do not adequately reflect the probable effectsaval blockade upon Inland transportation.

These bottlenecks, all within bombing range of US land and carrier-based aircraft, provideail targets for bombing and someaterfor aerial mining.

hese potential targets can be divided into five general categories, as follows: "

a. Rail and water links with the Trans-Siberian Railway. At present there are only three routes by which heavy overlandfrom the USSR can be brought into Communist China and over whichChinese shipments can move to thehe rail line from Man-chouli on thc Westernhe rail line from Sui-fen-ho on the east to the rail net aroundinanchuria;he Sun-gari River, which links Harbin with the Trans-Siberian Railway on Manchuria'sborder. An additional rail line is infrom the Trans-Siberian Railway near Vladivostok in North Korea, where it Joins the Korean rail net, which Ln turn has aat Tu Men with the Manchurian railIn the eventaval blockade of the China coast, these already important routes would obviously be of critical significance. Mo alternate rail routing Is possible over theiles from Man-chou-li to Harbin, while the first junction point on the Sul-fen-ho-Harbin line isiles from the border.

The total effectshinese NaUonallst blockade on Communist China's seabornetrade might be considerably greater,at least, than suggested by theirListed above. Charter and insurance rates would rise and non-Communist ship owners would be unlikely to charter their ships for trade with the blockaded ports.

Communist reactionaval blockade would almost certainly Include an intense campaign of political warfare that would probably include any or all of the measures noted above in the case of an embargo. In addition. Communist China would almost certainly commit its air and naval forces against the blockading forces with covertassistance and might launch attacks against Hong Kong and/or Macau,If these territories were in any waythe blockading powers. The USSR might reactaval blockade by attempting to bring merchant ships Into Port Arthur and Dairen under Soviet naval escort, byto force the blockade at other points, or by waging mine and submarine warfare against the blockading forces. However, we believe that the USSR would be unlikely to initiate general war solely because of incidents arising out of attempts to force the blockade, but the USSR would exploit such incidents to create dissension among the non-Communist powers.

AIR AND NAVAl BOMBARDMENT OF INLAND TRANSPORTATIONarge-scale and sustained air and naval bombardment of key Chinese Communist transportation Uncs, in conjunctionaval blockade, could sharply reduce Chinese Communist militaryut would probably not in itself induce theCommunlsts toorean settlement on UN terms.

TheChinese would probably reacthinese Nationalist effort to bombard lines of communications by strengthening their air defenses in East China and might retaliate by air action against territory held by Nationalist China.
