Advisors for Foreign Trade
The role of the Advisors for Foreign Trade is to provide expert advice on economic and commercial matters if needed by the federal or regional governments. There is no obligation for them to provide free advice to private businesses, but you are of course free to contact them.
Honorary Consuls are, in principle, a first point of contact for consular matters. Their function is also to promote the economic and commercial relations between Belgium and the country where they are residing. The Honorary Consul helps to liaise with the Embassy in Bangkok, more in particular with the Consular Section and the Offices of the Trade Commissioners. As it's an honorary function however, they are not authorized to sign visa or to take any other important consular decisions, and as the Embassy in Bangkok is quite accessible, we would advice you to contact the Embassy in Bangkok directly for consular matters if you are in Thailand.
It's only in Cambodia that we would advice you to work through the Honorary Consulate for all consular matters (see the 'Who is Who' section for their contact details). In Burma/Myanmar and Laos, the French Embassy can help you for visa matters. For all other matters, the Embassy in Bangkok would again be the appropriate channel.
