|~ Kiet says to Brian as he locks him on the bus and escapes|
Kiet is the tertiary antagonist in Furious 7. He is a powerful martial artist who is the henchman of Mose Jakande. He was portrayed by actor Tony Jaa.
Following the capture of Ramsey, Kiet is the head of Mose Jakande's convoy transporting her to the terrorist waiting on the other end of the path in the Caucasus Mountains. When he realizes that they're being followed by Dominic Toretto and his crew, he attempts to kill them with the arsenal equipped on their vehicle. Despite his efforts, Dominic and the others are able to destroy the back of their transport, allowing Brian O'Conner to board.
Kiet fights Brian, preventing him reaching Ramsey before he is knocked unconscious. Kiet regains consciousness as their transport heads for the edge of the cliff. Both Kiet and Brian head for the back of the bus, but Kiet reaches the end first. He closes the gate that traps Brian at the front and mocks him for being "too slow". Kiet escapes from the bus right before it goes over a cliff.
Later on, Kiet is seen assisting Jakande and his mercenaries when they ambush Dominic and Brian, along with government operative Mr Nobody and his unit, during their attempt to capture Deckard Shaw at his hideout; it turned out that Deckard had formed an alliance with Jakanade. In the ensuing gunfight, Kiet manages to shoot Mr. Nobody whilst killing a number of his agents in the process before leaving with Jakande and the God's Eye they have regained.
As time passes, Kiet is sent after Brian following the destruction of the first radio tower that allowed Ramsey to partially hack her device, the God's Eye. He manages to intercept Brian half way to his destination to the next radio tower. Brian evades him at first, closing a a rolling shutter down behind him as he rolled into the next room, killing several of Kiet's men in the process with his firearm.
Half way up the stairway, Kiet intercepts Brian again and knocks him down. The two go sliding down the stairs on the door and crash below. Kiet attempts to crush Brian several times with nearby objects. However, at the last second, Brian hooks Kiet's belt to a weight and kicks it down into an elevator shaft, which drags Kiet along with it to his death. Before getting killed though, Brian yells out to him: "Too slow!" like he did in the mounts as payback.
- Although the tertiary antagonist in the film, Kiet can also be considered as a minor character when only having three appearances.
- Kiet was also considered the main antagonist to Brian O'Conner due to the fact that he battled him throughout the entire film and appeared as one of the final enemies in the movie along with Deckard Shaw and Mose Jakande.
- His death is similar to Mai Lihn from Live Free or Die Hard.
