In China's 2006 Action Plan of IPR Protection, it announced its plan to revise the Regulations on Patent "in order to standardize the conduct of patent agents, safeguard the normal order of the patent agency industry, and protect the legitimate rights and interests of interested parties." The old regulations were after nearly twenty years deemed out of touch with reality.
The State Council has issued the Regulations on Patent Agency (Draft Amendments for Examination), reported by SIPO and solicited opinions "of all walks of life" before
September 25, 2010 March 10, 2011.
The regulations state how someone can become a patent agent, what are the educational requirements, how a patent agency should be run and what is not allowed for agents and agencies. It is clear that the self-regulatory industry group All-China Patent Agents Association plays an important role.
The Chinese version you can see here. If someone has an English version let me now.
