Since September 2018, the State Administration for Market Regulation ("SAMR"), the consolidated Chinese competition authority, has strengthened its enforcement of the China Anti-Monopoly Law (the "AML"). Given the increasing importance of antitrust law compliance in China, business operators should: 1. ensure there is a compliance program in place and that it extends to all necessary areas of the business; 2. check that the compliance program has been reviewed recently and, if not, see if it needs to be refreshed, particularly in view of new enforcement developments; and 3. prepare in advance in order to help the business team avoid or mitigate the antitrust risk in daily operations, particularly given current US-China trade tensions.
