Akamaro k'ubukungu 
Inzuzi z'umugezi wa Kasai zikuraho inzitizi nka cataracte n'ibyatsi byo mu ruzi, bigatuma bigenda cyane. Borohereza urwego rwo gutwara abantu no gukora imiyoboro ikomeye yubucuruzi. Uruhare rw'umugezi mu gutwara no mu bucuruzi rwagaragaye cyane mu gihe cyabanjirije ubukoloni igihe ubucuruzi bw'abacakara bwari bwemewe. Abacuruzi b'abacakara bakoresheje imwe mu masoko akomeye, Umugezi wa Kwango, kugira ngo bayobore ishyamba ry’imvura ry’uburinganire, bafata imbata maze basubira mu nyanja ya Atalantika aho bari bafungiye amato yabo. Ntabwo bivuguruzanya cyane ko ubwami bwaho bwari hafi yuruzi rwa Kasai bwashyigikiraga ubucuruzi bwabacakara. Urugero, ubwami bwa Rund, bwatanze byoroshye imbata kubacuruzi bazwi cyane nka John Matthews, umucuruzi uzwi cyane w’abacuruzi b’abongereza. Ibi bikorwa, nubwo byabaye hagati yikinyejana cya 18 na 19, byasize ingaruka zirambye mu turere bagaragaye cyane, nko hagati ya Kwango ninzuzi za Kwilu. Abaturage ntibigeze bakira neza, kubera ko ubucucike bw’abaturage buri munsi y’uturere tutarimo ubucuruzi bw’abacakara. Ikintu cyashobokaga cyane inyungu z’Abongereza n’Abanyaportigale mu ruzi rwa Kasai ni ukubera diyama ya alluvial iryamye mu buriri bukungahaye cyane cyane ku nkombe y’umugezi. Ibigega byinshi biri ku buriri bw’umugezi munini, uruzi rwa Kwango. Mubyukuri, birasanzwe kumva imvugo "umutima wa diyama wo mu burasirazuba bwa Angola y'Amajyaruguru" yakoreshejwe yerekeza ku kibaya cy'Uruzi rwa Kwango. Ni ukubera ko ibitanda bya diyama alluvial biboneka muri kano karere aribyo bikize cyane muri Angola.
