Summary: In recent weeks we have noted a number of Communist troop movements in Laos, both into the Plaine des Jarres area and farther south in the area adjacent to the Seventeenth Parallel. These deployments have put the enemy in a considerably better position to launch an offensive either out of the Plaine or toward the Mekong. Coupled with the continuing development of Hanoi's infiltration apparatus, they also could supply a significant increment to the already substantial - and as yet not fully committed - Viet Cong strength in the northern provinces of South Vietnam. With the continuing long-range build-up of a logistic base in the Kunming and Canton military districts which began in nineteen sixty, and the short-range build-up of air strength in these districts and in North Vietnam which was triggered by the Tonkin Gulf episodes last summer, the Communists are increasingly able both to defend against any U-S air attacks on North Vietnam and to retaliate by raising the level of ground action in Laos and South Vietnam.

Recently work on this line was given a higher priority, but it will still be several years before it is completed. Two. While this construction has been going forward, Peiping has maintained a fairly large ground force in both the Kunming and Canton…
