CHC Consultancy Services Ltd. was a company set up over ten years ago by Dutch entrepreneurs Nic Pannekeet and Gijsbert de Bruin. Amsterdam RAI has been one of CHC's early customers and started to use CHC services (market research and partner search) as soon as 1999. Over the years the relationship evolved and intensified between the two companies and as of 2003 CHC was appointed the sole representative and trade show agent for all of RAI's international trade shows in the greater China area.

Due to the successful cooperation, the RAI and CHC expanded their scope of activities. CHC became the local PEO for the ISSA/Interclean China and the project partner of the Aquatech China show. In order to enable this growth, CHC established a new structure in 2006 under the name of CHC Expo Services Ltd which became an independent conference and trade show organizer.

The company has since then expanded rapidly, is involved in multiple projects and currently employs 25+ professionals from the exhibition industry.
