Excerpts from Books and Wikipedia
"With five neighbors, Congo (the “other” [former French] Congo) could be a major transit hub for this region, especially for DRCongo, if it ever recovers from civil war. Its capital, Brazzaville, lies just across the Congo River from Kinshasa and is linked to the port of Pointe Noire by road and railway. But devastating, unceasing power struggles have thus far neutralized Congo’s geographic advantages." [Geography: Realms, Regions, and Concepts, 17th Edition, p. 316]
