White & Case is branching out from the oil-and-gas focus of its new Houston office, adding  international arbitration to the mix with partner Jorge Mattamouros, who joined the firm on Thursday from King & Spalding‘s office in the city.

Mattamouros represents clients in commercial arbitrations, investor-state disputes and arbitration-related litigation. He has worked in the Latin America and Lusophone region, which includes countries where Portuguese is spoken, such as Angola, Brazil and Mozambique.
