To be fair, I'd say your best bet is to stay in Canada and get your experience there. The minimum amount of time you'll need to accumulate the necessary experience to work in China is probably around 5/6 years.
Get a career going in Canada, then try to make the move to a medium size jet as quickly as possible (here lies the biggest variable in this entire project), get a command and collect the hours. Once reaching the hours, go for it.
Other way would be to collect a number of hours enough to apply to different Asian carriers as an FO to gain experience there, possibly upgrade to PIC (there's the issue here, as you mentionned).
Although I can't personally testify, from everything I've read on here, DO NOT GO TO CHINA AS AN FO (some would even argue to not go as a captain either, but what do I know)
Good luck, it's a rather long term project you have there
