The global PCO officially launched the service in India, China and the Middle East in January, following a 12-month pilot scheme.
The delegate acquisition centres in Dubai, Delhi and Beijing have generated more than £370,000 in new delegate revenue for association client events in the past year. Latin America will be the fourth 'emerging destination' to be added in June.
MCI's Ajay Bhojwani, deputy managing director of MCI Middle East, said: "Revenue from delegate registration typically represents between 30 to 50 per cent of total international conference revenues. With the economic situation getting tougher and associations facing more competition for conferences, revenues from registrations are constantly sliding down and PCOs are under greater pressure to solve this problem.
"Looking at these challenges, the delegate boosting service creates a win-win situation for associations and us. It's a local approach for a global meeting. Delegates in emerging destinations have a real thirst for learning and best practice, which is why we have targeted these countries first."
Bhojwani adds: "We applied the strategy to the World Cardiology Congress in April and had great results. So when we go to Melbourne with the congress in 2014 we will already have established relationships with delegates through the acquisition centres, so we can start to build on this. We have now activated the service for the European League Against Rheumatism."
