Christine Daya

Co-Chair, CFIUS and Global FDI Practice

Christine Daya's practice focuses on a variety of laws and policy at the intersection of national security and global trade.  For over a decade, Christine has served as a trusted advisor to major U.S. and non-U.S. multinational clients on foreign direct investment (CFIUS), economic sanctions (OFAC), supply chain risk management (CBP), and congressional investigations. 

Christine develops a deep understanding of her clients’ business and draws on her strong knowledge of relevant laws and regulations in rapidly-changing fields to advise on challenging, high-stakes, government-facing matters.  She represents clients in a wide range of industries, including financial services, emerging technology, consumer goods, pharmaceuticals, energy, manufacturing, insurance, real estate, telecommunications, and others.

For hundreds of cross-border investments, Christine has advised on the requirement or recommendation to file with CFIUS and on the allocation of CFIUS risk in transaction documents. She has effectively and efficiently cleared the CFIUS process for dozens of clients and negotiated national security agreements if needed to obtain CFIUS clearance.

Christine also has substantial experience with sanctions matters before the Office of Foreign Assets Control (OFAC).  She advises clients on primary and secondary sanctions compliance and risk, designs and implements compliance policies and procedures, leads complex internal investigations related to potential violations, and has had considerable success with the submission of voluntary self-disclosures and license applications to OFAC.

Additionally, Christine counsels clients on global supply chain risk management and forced labor legal liability.  She works with clients to gain visibility into their supply chains, identify and remedy risk, and respond to CBP enforcement of the Uyghur Forced Labor Prevention Act (UFLPA).  

Finally, Christine has represented companies and individuals in high-profile congressional investigations, working with clients on scoping of requests, witness preparation, strategy development, and document production.
