The activities of large firms can impact multiple markets in foreign jurisdictions, expanding the reach for anticompetitive conduct to have cross-border effects. A purely domestic focus on antitrust policy is therefore no longer sufficient. The international community has tried and tested various approaches to effectively cooperate and to tackle antitrust issues with a global dimension. Of late, significant progress has been made, particularly among developed nations in relation to case-specific cooperation in international cartel investigations and cross-border merger reviews. This paper examines the experiences gained so far in competition law enforcement cooperation, highlighting approaches taken to deepen cooperation in enforcement practice and share information and best practices in order to effectively investigate market activities involving transnational elements.enOther
