As the threat of a China-U.S. trade war continues to escalate, an attorney who previously was head of Baker McKenzie’s China trade and supply chain practice group and of Deloitte’s global trade practice has launched a boutique law firm in Hong Kong.

William Marshall has founded William Marshall & Co., a firm that will focus on advising clients on customs audits and regulatory investigations in China, Hong Kong, and across the Asia Pacific. It will also advise on anti-dumping and anti-subsidy proceedings under World Trade Organization rules.
