General Act of Brussels (1968)
“ The contracting powers whose institutions recognize the existence of domestic slavery, and whose possessions, in consequence thereof, in or out of Africa, serve, in spite of the vigilance of the authorities, as places of destination for African slaves, pledge themselves to prohibit their importation, transit and departure, as well as the trade in slaves. The most active and the strictest supervision shall be enforced at all places where the arrival, transit, and departure of African slaves take place. ”
