This is quite off-topic, but one logical and appropriate thing to do is approach a consultancy firm in Malaysia that specialize in business development/regulation/IT to learn how to talk in their "native language".
Yes thanks. I am not doing exactly this but contacting an American who is well versed in Malayan culture, language, and has studied there. Beyond this, I think it is interesting to fomalize cultural differences to learn how to handle these situations.
