Prospective Economic Effects

I. Bloc isports froa edvacced Western5 billion annuallyaaount to about one-sixth of total in-port s, and their loss would noterious general iupoct upon the volume of Bloc production. The USSR, however, sees in this trade considerable economic advontnae to itself and tto allies. In certain instances it provides thea with key inports. The USSR, for exac.ple, is currently buying advanced equipcttnt for its chenical and several other industries, and loss of these iuports wouldignificant effect upon the prospects for neetlnc planned goals in the industries affected over tho next year or so. The uost critical area of concern, however, is East Geraany, which obtains frou the KAT0 countries about one-sixth of its total loports, including oany products not readilyelsewhere. ull enbargo would cause considerablein the East Geruon econony, and it ciicht take up to six months for nornal Industrial growth to be resuoed.

would lay great stress on the contention that Japan was being asked to cwke sacrifices and run risks for reasons entirelyto its" own interests.

Tbe longer the West confined itself to on eribargo and other nonollitary counter-ueasurcs,re the Soviets would be Inclined to discount the possibilityater Western resort to orus.
