Since the beginning of the new century, several emerging markets have modernized and reformed their national competition laws. China is a good example of growth and maturity of emerging economies in antitrust enforcement. Just in a period of six years, the implementation of the AML becomes increasingly sophisticated and has already surpassed the infancy stage. China's experiences of antitrust regime undergo at least three phases: at the outset, merger control was the key area of enforcement, then monopoly agreements were gradually extended, and now the new territory - being the most controversial issues - the abuse of dominance has also been occupied. Due to a development approach instead of a pure efficiency approach, China does not directly copy the experiences of mature jurisdictions. Sometimes, local enforcement agencies have to make compromises among many different and even contradictory objectives. It is a sign of transition period. In the long run, enforcement of antitrust law should be autonomous from and prevail over the industry policy and other non-competition concerns.
