So, we are entering a new exiting phase; reports of chinese regulations start being implemented now. The government want to take control again of the supply; they are cracking down heavy on "the big 6" (main producers).
On top of that, they are seeing some progress of "controlling" the unlegal players in the market. I think they will gain more control this year, since they are very motivated to get the taxes AND reducing the pollution of these unlegal activities.
Don`t forget; in chinese culture/politic they have a 50-100 year perspective - they MUST adress enviromental issues and now they are leading the green-revolution, it`s necessary and urgent in todays politic.
