International Arbitration

We help you solve your cross-border disputes, no matter how complex

Clients from all sectors rely on the commercial understanding and international presence of our experienced international lawyers to resolve their most significant cross-border disputes. Our team is active in both commercial and investment treaty arbitrations, managing complex and novel matters.

Our specialist arbitration practitioners are based in key arbitral centres across Asia Pacific, Europe and the Middle East, and regularly represent clients before the world’s leading arbitral institutions as well as many other international and regional arbitration bodies.

Key distinguishing features of our international arbitration practice

  • We are China’s first international law firm able to practice Chinese, Hong Kong, English, Australian, US and a significant range of European laws
  • Our clients can tap into China arbitration resources of over 60 specialist lawyers based in 12 offices across the country (compared to the one or two offices of a few general practitioners, typical to our competitors). Where international arbitration involves Chinese elements, we supply clients with cross-office arbitration teams from our global network, so as to cover not just legal but also language and cultural aspects
  • Our arbitration specialists are recognised by clients and industry participants as being at the top of the field, with legal directories such as Chambers, Legal 500 and the Global Arbitration Review ranking us amongst the top international arbitration practices

  • We act both as counsel and arbitrators under the auspices of a wide range of arbitral rules and institutions, including the International Chamber of Commerce (ICC), the London Court of International Arbitration (LCIA), the China International Economic and Trade Arbitration Commission (CIETAC), the Hong Kong International Arbitration Centre (HKIAC), the Singapore International Arbitration Centre (SIAC), the United Nations Commission on International Trade Law (UNCITRAL), the Dubai International Arbitration Centre (DIAC), the Australian Centre of International Commercial Arbitration (ACICA), the Shenzhen Court of International Arbitration (SCIA), the Shanghai International Economic and Trade Arbitration Commission (SHIAC), the Kuala Lumpur Regional Centre for Arbitration (KLRCA), the Permanent Court of Arbitration (PCA), the London Maritime Arbitration Association (LMAA), the American Arbitration Association (AAA), the BANI Arbitration Centre, and the DIFC-LCIA Arbitration Centre.
