entering China with your own vehicle gets asked here about once a week. The general consensus seems to be, that it´s not 100% impossible, but will consume a ridiculous amount of time, nerves, and money - especially that last one in your case, cos you´d want to go all the way from Kazakhstan to SE Asia. That´s why most travellers decide to do something else.
And basically the same goes for Vietnam these days. Or of course you can try your luck on an "unofficial" entry at the borders, but I wouldn´t count on succeeding.
The road actually seems to be more freely open to Mongolia & Russian Far East (but you don´t want to be caught out by winter over there). Or also to India, provided you have the carnet, and then you can freight the bike to SE Asia. I did that 3 years ago, and had a great time.
