Kasumbalesa is a major crossing point for both human traffic and cargo for both Democratic Republic of the Congo and Zambia. It is the main conduit of trade that amounted to US$575 million that DR Congo imported from Zambia compared to US$1.7 billion that Zambia imported from its northern neighbor, based on 2015 data. An average of over 500 long-haul cargo trucks are cleared daily in each direction. In April 2019, the traffic at the border crossing snarled, leading to congestion on both sides of the border.
