“Take the Casino's management and ownership team to discuss a buyout with the Duggan Investment Trust. Be ready for a tough negotiation.”
— In-game description.
“Mr. Cheng has agreed to a meeting with the Duggan Family. I'm worried... it's a very complex situation. They're clearly not above some fairly heavy tactics.”
“Hey. Are you busy? There's been a development with the attempted buyout, and we may need your help. Please swing by my office as soon as you can.”
— Agatha's phone call
Go to the Management area inside The Diamond Casino & Resort to meet Ms. Baker.
The protagonists are contacted by Ms. Baker, who informs them about the attempted buyout of the casino by the Duggan Crime Family and seeks out their help. When they enter her office, they are greeted by her, Tao Cheng, and his translator. Ms. Baker tells the team that Tao has agreed to a meeting with the Duggan family, but is worried about how the buyout will go. Ms. Baker asks the team to come along with them to the meeting. Tao is now shown as more aggressive and serious than his usual drunken self, having been trained by Brucie Kibbutz, who Tao appointed as his personal trainer. His translator informs the team that Tao began a regime of high-pace exercises and bull shark testosterone, making him aggressive in the process. After Ms. Baker requests Debbie to have two Cognoscentis brought to the front of the casino, she and the team leave her office.
The team then drives Ms. Baker, Tao, and his translator to the meeting at Marlowe Vineyards. During the drive, they explain to the team the context behind the meeting, and the shadiness of the Duggan family. Once they arrive at the meeting, they are greeted by one of Duggan's bodyguards, who leads the group to meet up with Avery Duggan and his nephew Thornton Duggan. Avery tells Tao that he wants to buy the casino, wanting to discuss a fair price. Tao dismisses Avery's offer, with Tao's translator telling Avery the casino is not for sale. Avery tells them that they are making a very big mistake, and tells Thornton to take Ms. Baker to show her their expansion proposals that they were discussing about. Ms. Baker insists on staying, but Avery tells her that she should leave, reasoning that the deal is significantly above her pay grade. Ms. Baker acquiesces, and she and Thornton leave the meeting. The deal then turns sour as Avery's tone of voice becomes menacing and hostile, as he threatens Tao and his family. Tao then pulls out a pistol on Avery, officially triggering a violent conflict between the Triads and the Duggan family. Avery walks away from the meeting, and orders his guards to kill the group.
The team aids Tao and his translator in killing all of Avery's guards, who are seen arriving in Kamachos and Buzzard Attack Choppers, along with a pair of Caracara turreted trucks. In the middle of the shootout, Ms. Baker calls the team, who tells them that she was dropped off at the Pacific Bluffs Country Club, as the Chengs are members there. She asks them to come meet her at the club, while also questioning the sound of gunfire in the background. After the team kills all of Avery's guards, they, Tao, and his translator get into the Cognoscenti, and make a getaway to the country club while also dealing with more of Avery's guards.
The team, Tao, and his translator manage to successfully escape from Avery's men and they arrive at the country club. Ms. Baker asks how the meeting went, with Tao's translator telling her that it didn't go very well, and Tao declaring war against the Duggans. Ms. Baker thanks the team for their help, before going inside the country club.

Oh hey, good to see you. Listen... Mr. Cheng has agreed to a meeting with the Duggan Family. I'm worried... it's a very complex situation. They're clearly not above some fairly heavy tactics... and given the dubious nature of the Cheng's fortune I can't really ask for help. Can you come with us? Thank you.
Take us to the Marlowe Winery. You know what we are doing there? We are meeting Avery and Thornton Duggan, Texan investors. They have been trying to buy the casino.
Mr. Cheng... l-laments their methods. They have been very aggressive. Very dishonest. A hostile takeover. With dirty tricks. They were behind all the bad behavior at The Diamond recently... except for Mr. Cheng's.
The trainer... Brucie... he said he would work on Mr. Cheng's mind and body... so far is just high intensity training, lots of performance enhancing drugs, and very little mindfulness.
Mr. Cheng is very excited. It is very important meeting. If we can persuade them the casino is not for sale... maybe they will go away. And leave us to exploit Americans' gambling and alcohol addictions in the name of entertainment in peace.
Neither me nor my nephew have a problem that I'm aware of... we love China. Always have... ever since I ate my first egg roll. Well you see I never liked eggs... and an egg roll don't have eggs in it. I thought to myself... I like China... I just do.
It's not a problem, Thornton. Now now, boy... you're gonna sell us your casino... and don't get no confusion about that. See I want it... so all we are here to discuss is a fair price.
You boys are making a very big mistake. Thornton, would you excuse us for a moment? And why don't you take Miss... it is Miss, ain't it? Miss Agatha Baker, and show her the expansion proposals we were discussing.
Well what was that? A ball buster? I don't know... Anyway, Mr. Cheng... I wanna lay my cards on the table. I don't give two fucks about who your family is... or how many ninjas you got up your sleeve. Am I making myself clear?
Where I come from... you don't get to pull a gun unless you're willing to use it, but maybe you do things differently in your parts. Now when I return we will continue this conversation as gentlemen.
Hello, what's happening? They dropped me at the Pacific Bluffs Country Club, the Chengs are members here. Hello? What's that noise? Get over here when you can.
These bastards want to fuck with me... with me... Tao Cheng... they want a war... they got a war... I bring it... I fucking bring it... where's that Brucie guy?
— Tao Cheng. (English: "I almost got killed at this country club before. Once is enough already!")}
During the mission, when driving Tao and his translator to the Pacific Bluffs country club to meet up with Agatha Baker, Tao says "I almost got killed at this country club once already. Never again." This references The Third Way, the "Option C" Ending mission from Grand Theft Auto V, where Franklin Clinton drives to the same country club, where Tao and his father Wei Cheng are. Wei and his tribe are seen getting in 3 cars, and Tao is seen walking out of the club. Franklin kills Wei and his tribe, but keeps Tao alive, so therefore confirming Option C as the canon ending of Grand Theft Auto V.
Furthermore in The Contract update, Michael De Santa and Trevor Philips are mentioned as being alive in 2021, once again confirming that The Third Way is the canon ending of Grand Theft Auto V.
