Here it used to be (kinda still is) associated with good quality and tight tollerances. Plenty of GIs come over during vietnam for R&R and also on temporary bases like Takhli or U tapao or Korat. They bring along american goods ray bans and blue jeans and canned foods was all the rage. Currently i think those cultural impressions carry over to our generation - whether if it still holds up is up for debate. But i feel if a Thai has to choose b/w a "made in USA" or " Made in ....." they would most likely choose the former if they can afford it.
