Difficulties at the DRC port of Matadi

In my last post, I talked about the competition between seaports for exports from the DRC.  The DRC's own port at Matadi wasn't mentioned.  There's an account on Matadi's difficulties at Radio Okapi.  In English (my translation from the French):

"Ships have difficulties docking recently in the international port of Matadi and Boma, following a fall in the water level and the lack of maintenance of the upper part of river Congo by Congolese Seaways (CVM)."
