Miami-based law firm Diaz Reus & Targ announced last month that it has partnered with Sao Paulo-based Guimaraes & Vieira de Mello Advogados. The association will allow Diaz Reus to expand its operations in Latin America. Currently, the firm operates an office in Caracas as well as a joint venture in Bogota. "We believe that investment opportunities in Brazil will occupy a great deal of our time," said Michael Diaz, the firm’s managing partner. "[Diaz Reus’] Dubai office is already seeking investors for a company in the Brazilian agro industrial sector. Also, the firm’s Shanghai and Dubai offices are in discussions with potential investors to explore oil in marginal fields with a Brazilian company." The firm also announced Monday that it has opened a new full-service office in Shanghai, the South Florida Business Journal reported.
