This article attempts to understand how the driving forces of the global economy — the European Union, the United States, and China — view and approach international antitrust. This will be done by analysing recent stances that they have taken as well as longer trends in their actions and inactions in terms of international cooperation on competition issues, whether at the level of political rhetoric, legislative action or by a shift in legal praxis. Reasons for underlying differences are analysed and potential areas for deeper cooperation are identified. The article concludes by suggesting possible developments for future global cooperation in international antitrust. Findings will aid in forecasting the future path for international antitrust.
