United States > Dispute resolution > International trade

Kirkland & Ellis LLP‘s work in this space straddles its international trade and national security practice and also its government, regulatory and international investigations group. As such, the firm’s focus on export controls, economic sanctions and national security spans an array of regulatory compliance, transactions, investigations and enforcement-related matters. In Washington DC, Ivan Schlager is widely revered as a leader for CFIUS reviews, and is often selected for this function even when the transactional work is handled elsewhere. Mario Mancuso, who operates between Washington DC and New York, handles CFIUS matters, export controls and economic sanctions and is a popular choice for private equity sponsors, as well as corporations and financial institutions. New York-based Zachary Brez advises on economic sanctions, export controls and anti-corruption issues. Chicago-based Nick Niles is also known for his experience with private equity clients.
