My company has made parts for this plane. The biggest problem they will have is the fuel efficiency. It's quite a bit heavier than the 737 or A320 and the engines will not compare to the new GE Leap X engines that will be the status quo in the industry for the next 10 to 20 years.
Parts and design of this plane are not solely Chinese. They will be able to enter the market but it will take years, maybe decades for them to steal major business from Boeing or Airbus. However, the aerospace industry is taking them very seriously and another one of the reasons for the push on the 737 Max and A320 Neo.
#10 - About 30% of Airbus is owned by France, Spain & Germany. It used to be about 50% but that changed around 2012.
