Unpopular opinion but I do wish that China could annex Myanmar and actually turn it into a functional state instead of a shithole filled with drugs, scams, crime and gangs that is dragging down all of south-east asia as a whole. Probably won't ever happen though, even though full control of Myanmar offers up the Indian ocean to China.
Full annexation will never happen, but I wonder why does China let neighboring allied countries like NK and Myanmar do whatever they want and turn into pseudo-failed states. Doesn't China have enough influence to strong arm this countries into win-win economical policies that can turn them into the equivalent of Thailand, Vietnam or Laos?
