It may be relatively small with 82 members, but the Belgium-Luxembourg Chamber of Commerce (BLCC) is disproportionately active - and uniquely unconventional.
Its president, Jean-Paul Cuvelier, is a former Belgium First Division footballer and national rally-driving champion who made his fortune in Hong Kong founding Alfa Technology, which manufactures 'designer' electronics, including the world's smallest DVD.
The chamber, meanwhile, is unique in many respects - not least because it represents two countries, and is open to membership from any nationality.
While many chambers invite financiers, politicians and government officials to speak at their monthly lunches, the BLCC prefers 'off the wall' adventurers.
'I hate listening to financiers and analysts,' says Mr Cuvelier. 'We have many opportunities to hear them, and they always tell you what to do when it's too late.'
The chamber is also famously outspoken at gatherings of the International Business Committee, a unique platform of discussion between the Hong Kong business community and government, usually chaired by Chief Secretary Donald Tsang Yam-kuen.
These meetings allow 'extremely frank' exchanges of opinion between business community leaders and the government. 'We really say what we think,' says Mr Cuvelier. 'I don't know anywhere else in the world where businessmen meet the government like this.'
