China was getting better for a long time. XI is changing that. Change is slow though and he is not rushing corruption though it seems to be increasing. He has purged some corrupt people as well making things slightly better in the short term - but he values loyalty over competence and so his short term changes are for less corruption but long term increase it.

That is China is a complex country and books (which are not written and many cannot be for decades yet) are needed to understand this, not a short comment box. [This applies to every other country anyone here mentions]
