Demolition companies in China?

Hi I'm a new member here, I thought I would join to ask some of the professionals here.
So my questions are
#1 is most demolition in China done by state owned enterprises
#2 how does a foreign demolition firm enter the Chinese market
#3 how corrupt is it, do you need to bribe the communist official to get a contract?
I have lurked this forum for some time and I'm amazed at the wealth of information here so I figured this would be the right place to ask.
Please note that I am NOT a demolition...
