Winston & Strawn has become the latest U.S. firm to reassess its role in Asia, as it has seen several attorneys in Hong Kong and Shanghai leave and has shuttered its offices in Beijing and Taipei.

The two offices closed in late 2016, and core lawyers were transferred to the firm’s two remaining Asian offices in Hong Kong and Shanghai. Senior intellectual property associate Gino Cheng moved to Hong Kong from Taipei. And several other lawyers, including former resident partner Horng-Dar Lin, have left the firm.
