Chris has been awarded many accolades, including the highest ranking by Chambers Global and as a Washingtonian “Star of the Bar.” He has been invited by the U.S., British and Italian governments to address CFIUS and other regulatory aspects of foreign direct investment in the United States, and has been quoted in prominent publications including The Financial Times, The Washington Post, The Deal, China Legal Review and American Law Daily.
