The Benelux Parliament provides the governments with advice on economic and cross-frontier cooperation. Its recommendations may also concern other matters if common interests or current events so dictate.
The Benelux Parliament works alongside supraregional and supranational organizations such as the Interregional Parliamentary Council, the Nordic Council (Denmark, Sweden, Finland, Norway and Iceland), the Baltic Assembly (Latvia, Lithuania, Estonia) and the Visegrad countries (Poland, Hungary, the Czech Republic and Slovakia). The Benelux Parliament is also forging links with groups of countries that wish to form a mutual cooperation along the lines of the Benelux system. For instance, the Benelux Parliament has contacts with the German Land North Rhine-Westphalia and with organizations of African countries, Andes countries and the countries of the Black Sea.
The Benelux Parliament also keeps the 3 governments informed about the opinions that move in the parliamentary assemblies from which its members originate.
