In many jurisdictions, ad hoc arbitration is not common. In mainland China, for example, the Arbitration Law stipulates that an arbitration agreement must appoint an arbitration commission. Therefore, arbitration agreements providing for ad hoc domestic arbitrations are generally considered invalid in China. However, in recent years, China`s Supreme People`s Court has issued an “opinion on the granting of legal protection for the development of pilot free trade zones,” considered an ad hoc arbitration in China. Last year, the Hengqin New Zone Administrative Committee and the Zhuhai Arbitration Commission jointly issued the “Ad Hoc Arbitration Rules of (Guandong) Pilot Free Trade Zone Hengqin Area of Zhuhai”. .
