Work highlights

Acted as sanctions counsel to Yandex N.V. on its high-stakes, extremely complex exit from Russia, and obtained the OFAC license required to complete the divestment. This was the largest Russia divestment since the invasion of Ukraine, with a transaction value of over US$5 billion.
Secured a victory for Arkema Inc., a major global chemical corporation and lone US producer of R-32, when the US International Trade Commission (ITC) determined the industry was materially injured by Chinese imports. As a result of the final determination, antidumping duties of between 161% and 211% were imposed.
