Winston & Strawn has added a partner in Hong Kong.

Former Orrick, Herrington & Sutcliffe Hong Kong partner Marco Pocci has joined the Chicago-based firm’s energy team.

Pocci had previously been a part of Orrick’s mergers and acquisitions and private equity group, advising on cross-border transactions, restructurings and other corporate issues. In addition, he also acts for clients investing in emerging markets, particularly China.

Previously based in Rome, Pocci moved to Orrick when he joined his solo practice with the San Francisco-based firm in 2006.

Winston & Strawn now has 16 lawyers, including four partners, in its Hong Kong office. The firm employs about 850 lawyers in 17 offices worldwide.
