Later on, Thornton, growing tired of Avery's increasingly destructive methods (which also risk their family collapsing) betrays him and hires associates of Tao Cheng to kill his uncle. When the Duggan family accepts to meet with Tao, the meeting goes sour, and Avery orders his henchmen to kill Tao, triggering a war between the Duggan Family and the Cheng Family, which leads to the destruction of Avery's assets and the assault on the Diamond Casino & Resort, which is then repelled by the protagonists.
However, the family immediately runs into trouble with the Duggan Crime Family who want to destroy the casino also by employing underhanded tactics to sabotage it, all in order to buy it back at a cheap price. In July 2019, after five years investing, the Cheng Family finally finished building the Diamond Casino & Resort business in Los Santos, which is then put under Tao Cheng's management under his uncle's orders from Hong Kong.
