You acquaint commercial logging with colonisation- thats well rich. Back in the mid 1800's though the UK was pretty cosy with the Siamese government because they were seen as a buffer to French expansion in Indochina.

US involvement with Thailand extends well beyond commercial logging and involves the Modern era, including GM plants and former military bases in Korat, Ubon Ratchathani, Udon Thani and Nakhom Phanom. Regular traffic of USN ships too, which helps keep Pattaya and Isaan well fed.
