With a core team that has practiced together for more than 30 years, Curtis, Mallet-Prevost, Colt & Mosle LLP provides a high degree of experience and knowledge to a strong and loyal client base of foreign exporters and governments in many of their highest-profile trade disputes. Although it has a smaller international footprint than many of the ranked firms, its offices in Geneva and Beijing are of great assistance to clients in, respectively, WTO matters and the many China-related issues. Team head Daniel Porter regularly leads on the most significant matters handled by the firm, such as the ongoing representation of LG Electronics in its trade litigation. This work has recently included defending the company in relation to safeguard actions targeting the importation of washing machines and solar panels. Matthew McCullough has a flourishing reputation in the market, having achieved some significant victories for corporates and foreign governments in subsidies cases. As well as handling domestic investigations, McCullough, alongside Porter, has also been a pivotal part of the firm's growth in the WTO arena, where the Chinese government is a significant client. James Durling rounds out the team at partner level, while counsel Antonio Riva Palacio Lavin has expertise advising on matters with a Latin America nexus, as well as on China matters by virtue of his role as the firm's chief representative of the Beijing office. William Barringer  joined Morris, Manning & Martin, LLP in April 2018. Named attorneys are based out of Washington DC, unless otherwise stated.
