Featured Topic – Foreign Direct Investment

Foreign direct investment (FDI) regimes have proliferated in response to Covid-19 and other geopolitical shocks as Governments worldwide have become increasingly protective of domestic sectors with strategic value. Our Antitrust Group has extensive experience in navigating the expanding global FDI landscape, and coordinating multi-jurisdictional clearances in tandem with the merger control process and any CFIUS review. We create the strategy to help our clients plan and execute complex cross-border deals with confidence and in a timely fashion. This expertise is especially valuable in today’s assertive enforcement environment.
