This would be the Nieuwe Afrikaansche Handelsvennootschap (New African Trade Association), the Dutch trading-house which was once the largest trading company on the Congo coast and the second largest on the Congo River after the Société Anonyme Belge.

During the 1880s, the company had operated on Stanley Pool and the Upper Congo. However, its relations with the Congo Free State deteriorated rapidly after 1888, and the company was forced to move its headquarters from Banana to Cabinda and transfer many of its trading factories to French and Portuguese territory.
