Tang Lin Zao, or better known by his surname Zao, is a major antagonist in the 2002 James Bond film Die Another Day. He is the right-hand man of Gustav Graves until the events of the film.
Defeat at Moon's Base
Bond originally met Zao in North Korea, where Bond arrives disguised as a diamond smuggler named Van Bierk while making a deal with Colonel Tan-Sun Moon, who is selling high tech weapons in exchange for conflict diamond. Despite Bond handing over the diamonds to Moon, the suspicious Zao checks his identity with Moon's western associate and finds out that Bond is a British spy sent to kill Moon. When he tells Moon about this, Moon blows up the helicopter in which Bond arrived and plans to kill Bond as well, but Zao is then called by Moon's father General Moon, who tells him that he will arrive at their base soon. Moon and his men then quickly leave the base with the hovercrafts and weapons, so that his father doesn't find out about his weapon dealing. He leaves Bond to be shot by his men, but the agent escapes by blowing up the diamond suitcase, knocking over Zao and the other Korean soldiers, and fleeing with the last remaining hovercraft. Zao's face is left being disfigured by several diamonds embedded into his face.
Exchanged for Bond
Zao was captured some time later by the British Secret Service, while he was about to blow up a summit between China and South Korea, killing three Chinese agents before getting caught.
Initially believing that he is to be executed, Bond is surprised when the soldiers instead drive off, leaving him alone on the bridge. Upon realizing that Zao is being traded in exchange for Bond's life, Bond vows to make Zao pay by saying that his time will come soon, but not before Zao vows that it won't be soon as Bond's.
After fleeing from the MI6, who think that Bond gave up critical information while he was interrogated, Bond meets a Chinese agent, claiming that he will kill Zao for them if they manage to get him into North Korea. When asked what is in it for him, Bond answers that Zao has information he needs, namely the identity of Moon's source in the west. The agent leaves the room to discuss the situation with Beijing, and returns to Bond, sending him to Havana instead of North Korea, as Zao has been spotted there.
Clinic at Cuba
Bond's sources at Havanna lead Bond to a private clinic at Los Organos (run by Dr. Alvarez), where Zao is supposed to be located. Arriving at the clinic, Bond finds a special tract behind a hidden door. There, he finds Zao, who is in the middle of a process to alter his appearance to make him appear to be of European heritage. Zao is unconscious, with a recorded message indoctrinating him to his new identity and language while he sleeps. However, Bond wakes Zao with the intention to find out who is paying for Zao's alterations as he thinks that this person is the same who set him up in North Korea. Zao kicks and engages in a short fight with Bond in which Bond is able to grab Zao's necklace and rip it off. Zao escapes from the room. Pursued by Bond and agent Jinx, he manages to get to his escape helicopter and escapes from the clinic while being shot at by the two agents.
While investigation the phial Zao wore around his neck, Bond finds out that it contains blood diamonds from Sierra Leone, engraves with the mark of diamond trader Gustav Graves.
When Bond arrives at Grave's place at Iceland, a palace made from pure ice only built for the demonstration of Icarus, he is greeted by Graves. While the guests entertain themselves inside, Graves is using his dream machine. He is interrupted by a man who is revealed to be Zao. Seeing his old friend for the first time after Zao's departure, Graves looks at his unfinished face and asks him who did that. Zao responds that it is Bond's work and Graves gleefully tells him that he has met Bond and Bond did not recognize him at all. Graves then asks Zao of news of his father and Zao tells him that General Moon still mourns his death.
When Jinx, who has also reached Island, breaks into the complex where Graves' chambers are located to kill Zao whom she expects to find him under the dream machine's mask. However, when she takes the mask off, Zao looks at her and Graves attacks her from behind, wearing the prototype of his Icarus suit. Graves knocks out Jinx. When Jinx awakens, she is strapped to a chair in a different part of the complex. Zao, who has been given the Icarus suit to interrogate Jinx first tortures her with the electricity created by the suit, then asks her why she came to kill him. Getting nothing but insults out of her, Zao tells Graves' henchman Mr. Kil to activate the lasers surrounding the chair to get Jinx to talk. When Jinx eventually passes out from the pain without having yielded any secrets, Zao realizes that she won't talk and gives Kil his gun to finish her of, but Kil tells him that he will use the laser. Zao then leaves Kil to it and exits the room.
After Bond has killed Mr. Kil and saved Jinx, she tells him that Zao is here and that he brought the dream machine from Cuba. However, finally realizing who Graves truly is, responds that Zao didn't bring the machine, it was brought here before by Zao's master Tan-Sun Moon, now going under the alias Gustav Graves.
Hunting Bond on Iceland
When Bond is captured by Graves and about to be killed, Bond goads Zao into hitting him into stomach in order to allow him to fall to the ground. Using a special ring he got from MI6's quartermaster, he breaks the glass panel that covers the entire floor in order to fall into the lower floor. As Bond runs off, Graves orders Zao to follow and kill him but Bond escapes with Grave's speeder, driving off into the ice plains at insane speed. When Zao returns and tells Graves that Bond escaped, Graves decides to unleash Icarus. To that end, Zao brings over General Dong, General Li & General Han for the demonstration.
While Graves hunts Bond down with Icarus, Zao and Miranda Frost go to the room where Jinx is imprisoned to kill her. When they open the door, Zao is immediately kicked in the face, but Miranda stops him from extracting revenge. After telling Jinx that Bond fled to save his own skin, they lock the door again to kill Jinx by the destruction of the palace.
When they believe Bond to be dead, Graves leaves Zao with a minimal force to watch over the final preparations at the palace, intending for him to follow after they are done. Zao, Frost and the rest then leave by plane.
Ice Race and Death
When Bond, hidden in his invisible car, tries to find Jinx' location, one of Zao's man crushes into him with his snowboard. Seeing this, Zao realizes that Bond is among them. Bond drives off, but is pursued by Zao, who drives an equally powered and modified car. Being able to see Bond through the thermal vision of his car, Zao shoots at Bond with mini-guns attached to his car, causing Bond's camouflage mode to malfunction. Racing each other across the frozen lake, Bond and Zao shoot each other with missiles but miss. Zao manages to turn Bond's car around but Bond gets himself back up by ejecting the passenger seat.
During the race, Bond sees that Graves has activated Icarus and aimed it at the ice palace, in which Jinx is still imprisoned. Followed by Zao, he drives towards the palace and breaks through the front doors. Inside, Bond drives up a ramp to the first floor where he waits for Zao. When Zao arrives, he sees Bond's car parked straight in front of him. Activating blades at his car's front, Zao drives at Bond, intending to impale him. When Bond uses his camouflage mode again, Zao is still confident because he knows that Bond is only invisible with no chance to disappear but Bond uses special spikes to partially drive up the wall, which causes Zao to screamingly drive over the edge of the balcony at which Bond had waited. Slamming through the ice into the water below, Zao manages to get out of his car, but when he reaches the surface Bond shoots a ice chandelier which falls onto Zao, killing him instantly.
