Wing So


Call: 2020

Wing has a focus on international arbitration and cross-border litigation, covering mainly commercial, construction, maritime, and aviation disputes, and more recently also investment disputes. He also has a particular expertise on costs disputes, and experience with town planning and licensing work. Due to his previous work experience, he is most frequently instructed in cases involving PRC SOEs and/or entities from Russia, Ukraine, or other CIS Countries. In addition, due to his experience in legal academia and university management, he has a background in higher education law, and Islamic and Hindu succession law.

Prior to joining the Hong Kong Bar, Wing has been a legal academic conducting research and teaching around the globe since 2010, including at Oxford, New Delhi, Luxembourg, Moscow, Kazan, Beijing, and Hong Kong, and previously acted as a legal advisor and expert witness for private clients for years in this capacity. He was formerly a judicial assistant of the Court of Final Appeal, and also served under the judge-in-chief of the Construction & Arbitration List of the High Court of Hong Kong. He also acts as an arbitrator.

He is one of the co-authors of the leading English textbook on the law of costs, Friston on Costs (3rd edn OUP 2019), building upon his doctoral research on the area. He was appointed as a foreign legal expert by the Ministry of Science & Technology of the PRC government since 2019. Outside of his practice, he continues to regularly give lectures and supervise postgraduate and doctoral students from various law schools in PRC and Russia on civil procedure and international arbitration. He is currently a Distinguished Professor and Graduate Supervisor for civil procedure and international arbitration at the China University of Political Science & Law in Beijing, and a visiting professor at Lomonosov Moscow State University.
