Sydney Trains fleet to grow

I'm surprised at the fact that CRRC sells rolling stocks to Australia.
In Japan, it's avoided to purchase transportation tools from China for safety and political issues.
For example, in Okinawa, Japan, a bus company was backlashed for purchasing buses from China.
So, it would be difficult to import trains to Japan's metropolitan area from China.
