On 2 September 2011 the Chinese Ministry of Commerce (“MOFCOM”) published on its website a finalised set of merger assessment rules, the Provisional Rules on the Assessment of Competitive Effects of Concentrations of Business Operators. The merger assessment rules expand on the five factors to be considered under Article 27 of the PRC Anti-monopoly Law. The finalised rules amend an earlier draft by recognising the possibility of unilateral and coordinated effects, and countervailing power as a form of competitive pressure on the merging entity. The rules came into effect on 5 September 2011. According to the Director General of MOFCOM’s Anti-Monopoly Bureau, Mr Shang Ming, MOFCOM will promulgate three further rules on merger control within this, or next, year.
