The fact that China has a significant program going and growing in the future is more than I can say about any other Asian nation even try attempting such an expensive persuite is a positive. Doubters and skeptics can point to any obstacles they want to but deep down they know it's all about the program that counts. Boeing and Airbus can not grow without access to the Chinese market that's why they are nervous about ARJ21 and C919 because of the strength of the program and it's potential growth.
As I posted neither Boeing or Airbus gives a rat's a$$ about ARJ21 since neither companies are in the narrow body sector. I also doubt neither companies are worried about a plane that is still only on paper.
As for the Chinese market, since she is a member of WTO she will need to comply.
One more minor point, Mitsubishi Airplane is scheduled to make maiden flight of the MRJ this year which is a direct competitor of ARJ21. Again it may take time for her to gain type certificate but she already has 223 confirmed orders and another 184 as option orders so she has good appraisal so far.
