THAILAND (SIAM) 4. The Japanese occupation of Thailand will, subject to their being able to ship the commodities to Japan, assure the supply of some 48,000 tons of rubber p.a. and valuable supplies of tin from the provinces South of the Kra Isthmus. The rubber from Thailand will, together with that from Indo-China, provide Japan with all the supplies she needs and allow for some export to France or Germany. The quantity of tin available may be limited by immobilisation of mining machinery. Small but useful quantities of wolfram and zinc are also available.
