The defender pounced upon a goalkeeping error in stoppage time as his side beat Congo 3-1 in Kinshasa.
As he celebrated, he pointed to the sky and after the match he posted a social media tribute to Tiote, who tragically passed away earlier this month. Along with a picture of him wearing a t-shirt with the message 'Adieu Cheick Tiote', he wrote: "This goal is for you #CheikTiote. We will never forget you. RIP."
The victory was the perfect way for DR Congo to start their Africa Cup of Nations qualifying campaign. Villarreal's Cédric Bakambu scored twice before Mbemba wrapped up the win.
Mbemba scored his first Newcastle goal in the 3-0 success against Barnsley on the final day of last season.
