DR Congo progressed to the Africa Cup of Nations knockout stages and Tanzania bowed out after a 0-0 draw between the teams in Korhogo.
The second half saw Brentford’s Yoane Wissa denied by Tanzania goalkeeper Aishi Manula and send a further shot over as DR Congo drew a third game out of three in Group F.
Sebastien Desabre’s side finish second in the pool behind Morocco and will face Egypt in the last 16 on Sunday.
A turbulent campaign for Tanzania, which included head coach Adel Amrouche being suspended after making comments about Morocco’s football federation and assistant Hemed Suleiman stepping in as acting boss, concludes with them bottom with two points.
Former Chelsea man Gael Kakuta brought a comfortable catch out of Manula with an early free-kick before Tanzania captain Mbwana Samatta rifled a shot off target on the quarter-hour mark.
Manula got down to save a Wissa effort, although the forward was flagged offside.
And Manula then did well to come out and make a block with his legs in the 30th minute when Fiston Mayele was played in.
After the break, DR Congo’s efforts to break the deadlock included substitute Meschak Elia blazing a 73rd-minute shot into the stand when the ball fell to him in the box following a free-kick.
Five minutes later, Wissa attempted to send a lob over Manula, who managed to tip the ball away.
The Leopards’ late push continued with Cedric Bakambu heading too high and another Wissa shot fizzing just over before the final whistle confirmed Desabre’s men as through with another draw.
