You might be right, as I am far from having expert knowledge on china.  Although I feel I have enough insight into history to express that (emerging) superpowers are willing to destabilize regions and mold them in their favor. 
considering this:
You really have no standing ground, being German, questioning Chinese actions that could disturb world peace. 
I dont feel my opinions should matter less because of my nationality.
Ps:  afaik china historically was a meritocracy, even served as a role model for european philosophers during the enlightenment. but today?  nah man.  on economical level for sure, but politically it feels very ailing.  
but enough derailment, I am off for a long european weekend of doing fun european things.
