 The Belgian government also privatised many of the government-owned companies that were active in the colony (the Kilo-Moto mines, La Société Nationale des transport fluviaux..).After the First World War, priority was given to investments in transport infrastructure (such as the rail lines between Matadi and Léopoldville and Elisabethville and Port Francqui).From 1920 to 1932, 2.450 km of railroads were constructed.
