MOFCOM released the amended Guiding Opinions on Notification of Concentration of Undertakings (“Guiding Opinions”) on June 6, 2014. The amendments significantly expanded the content of the previous 2009 version of the Guiding Opinions. The number of articles in the Guiding Opinions is now 30, in comparison to 12 of the 2009 version. This is the third regulation on merger control issued by MOFCOM in 2014. Another merger control related regulation concerning the imposition restrictive conditions is currently being drafted and might be published this year as well. Among other things, four important areas of merger control filing that gave rise to a great deal of discussion in the past have now been clarified under the Guiding Opinions. These four areas include definition of control, calculation of turnover, status of joint venture in identifying concentration and pre-notification consultation.
