Bombardier made some contribution at best, but most part of our high speed rail still relied to our brilliant engineers.
And the most important technology for China's supercomputer is the interconnect between the bands, cpu isn't that important compared to this aspect. You know even Japan built the world fastest cpu, yet they are not able to build a supercomputer of that level now.
I suggest you to move along and stop taking away the credit of our success. If you believe that every achievement in the World should thank to white people's contribution, then i suggest you go to stormfront.org, here is not an appropriate place for you.
