The Supervisory Board of the EU-ASEAN Business Council consists of representatives of the European Chambers of Commerce in Southeast Asia, who are members of the Business Council (presently nine), and an equal number of MNC member representatives. Members of the Supervisory Board cannot be members of the Executive Board at the same time. Its current membership is therefore eighteen-strong.
The Supervisory Board has to meet at least twice per year, though it can meet more often if the Chairman of the Business Council deems it necessary.
