Hello Templar,
How's the weather in Tianjin and how is your Chinese?
Agile,
The best civillian and longest established course I know is by Bushcraft Expeditions who run a jungle course in Brunei and Thailand. The main man is Andy Wood who is very competent, ex-UK SF and who still runs courses for the military e.g tracking for the Gurkhas. He is by no means a Rambo type, quiet soft spoken guy with a dry sense of humour.
Recently started is a jungle course in Peninsular Malaysia by Australian Bob Cooper, who is mainly known for his desert work. However, Australians can do anything and most of Bobs assistants are ex-SASR so will have experience in the jungle anyway. In Malaysia, he is assisted by indigenous people and ex- Malaysian SF. Bob like Woody, is quiet and soft spoken. A great guy.
Another place, which I cannot vouch for but which others have enjoyed, is JEST the ex-US survival school in the Philipines. Instruction is by the Aeta people, aboriginals who assisted the now long gone US military instructors. Member ZDP159 has been there twice and raves about it.
My advice is avoid courses that seem Rambo-like run by loudmouth types. You are more likely to learn actual bushcraft that way and in a more sensitive way to the local people and environment.
BCUK people occassionally run trips to this part of the world and you could enquire on the forum about joining them though this tends to be a full member / mod thing.
Hope that helps.
