One of the founders of the former King & Wood has left to join another Chinese law firm, Commerce & Finance Law Offices.

Bai Yanchun specializes in initial public offerings and company restructuring matters for state-owned enterprises including PetroChina Co. Ltd., China Life Insurance Co. Ltd., State Grid Corp., Angang Steel Co. Ltd. and diesel engine maker Weichai Power Co. Ltd. He focuses particularly on the energy and infrastructure sector.

In 1993 Bai cofounded former King & Wood with current King & Wood Mallesons chairman Wang Junfeng and one other partner, Zhang Dongqing, who also remains at the firm. The trio had previously worked at Global Law Offices, a firm established by China Council for the Promotion of International Trade, a quasi-governmental trade body.

Bai could not be reached for comment yesterday. King & Wood Mallesons, the result of a 2011 combination between King & Wood and Australia’s Mallesons Stephen Jaques, did not respond to a request for comment.

Earlier in his career, Bai was a counsel in the since-closed Hong Kong office of Canadian firm Stikeman Elliott.

According to its website, Commerce & Finance has about 200 lawyers, including 70 partners. Unlike the larger, more general-practice King & Wood Mallesons, Commerce & Finance has focused almost exclusively on Chinese capital markets work.
