WLTCASF.SUBJ)228 i DECLASSIFIED NLT-85-19 - (Nxc lueno 7-21-57) Authority Date 8-12-57 THE WHITE HOUSE By DEB NLT WASHINGTON TOP UNCLASSIFIED January 4, 1952 SECURITY INFORMATION ARCHIVES TRUMAN "INATIONAL AND A RECORDS ADMIN MEMORANDUM FOR: gove The President Subject: Value of Dairen and Port Arthur to circumvent blockade of China coast An examination of the feasibility of circumventing a naval blockade of the China coast by using the ports of Dairen and Port Arthur has been made, as follows: Dairen is the largest port in Manchuria. Facilities are available to unload 26,400 long tons of cargo per day from ships alongside piers, plus 12,500 long tons, per day, from 25 Liberty-type ships anchored in the stream. There are 55 berths alongside piers at water depths from 16 to 32 feet and a total of 372 anchorage berths of various sizes. A double-tracked railroad, capacity 15,000 long tons, per day, and two improved highways, each having a capacity of 6-8000 long tons, per day, lead to Mukden. Port Arthur is located about 20 miles west-south- west of Dairen; is a minor commercial port with facilities to unload about 4900 long tons of cargo, per day, from ships alongside quays. A double-tracked railroad connects with the main Mukden-Dairen line and a road leads to Dairen. It is estimated that Communist China imported a minimum of 20,000 long tons a day by ship during 1951. If all of this amount went into Dairen and Port Arthur, it could be unloaded and transported away from the ports by rail, road and junks. Junks could carry packaged cargo to Taku and other ports west and north of the Shantung Promonotory without serious interference from blockading vessels. The only way to move significant amounts of material overland from the north to central and southern China is via the two main north-south railroads. One of these passes through Peiping and the other Tientsin; each has an estimated maximum capacity of 4,000 tons a day. TOP SECRET UNCLASSIRIEDITION
