There are 22 Belgian exclaves in the Netherlands and 6 Dutch exclaves located within the largest Belgian exclave. Such land distribution results in complexity of borders between the two countries.

There must be quite a few entrepreneurs in this town using its location and difference in laws to their own benefit.
