I think organized missions would be the best, along with some financial assistance to participate in those organized missions. From a cultural and linguistic point of view, it's not an easy thing to jump into, but having done it myself, I can say that neither the language nor the culture is that daunting. It's not that hard.
The Chinese do not like to deal with an agent. They like to deal with the principal in the business, so people running around saying they're agents, they have good connections, and they will do all kinds of good things for them doesn't work in China. They're much more sophisticated than that.
Trade missions, whereby the Canadian government can help Canadian manufacturers to actually sit down one on one with Chinese railway companies, would be good. There are a number of private railway companies. There's a big government ministry of railways, but there are a lot of smaller ones too, some privately owned by the state governments and some owned by industry. Government missions could bring the people there and acquaint these people, for the first time, with the fact that doing business with China is not as daunting or as difficult as it may seem.
