I think that's pretty obvious to all of us that current state in the world and regarding US/China relations isn't peacetime at all. Cold war or warm peace, that's more likely. So, I don't think that China making supercarriers for trawling in ECS or SCS makes sense. Why not send Shandong or Liaoning on an extended cruise? At least in Indian Ocean or central Pacific. If anything, Chinese crews will get more experience. Friends of China will be happy because of visits, and enemies not so much, but they hate China anyways.
