I look forward to supporting the important work of the ICC International Court of Arbitration, which is the premier arbitral institution worldwide for international commercial arbitration. The insights gained from this role will also benefit our clients and colleagues.” 

Chloé added: “The ICC International Court of Arbitration is the leading institution globally for international commercial disputes. Our appointments showcase the value our expertise in international arbitration has, and I am proud to represent our South Africa team at a global level.”
