The Flemish International Relations Minister, Geert Bourgeois (nationalist) has signed an agreement with the Catalan Government in Spain with a view to closer ties between the two regions.
Catalonia was recently granted a new autonomy status. This means that the region now enjoys greater powers and is able to sign international co-operation agreements.
The Senedd should have that power too. Unesco would be an appropriate body for Wales to sign an international agreement with.
