Lee Chaolan joined The King of Iron Fist Tournament 5 to exact revenge against Kazuya Mishima. Lee lost interest in the tournament, though, when he learned that it was actually Jinpachi Mishima who had started it. He returned to his home in the Bahamas.
The world fell into disarray at the hands of the Mishima Zaibatsu, led by Jin Kazama, and the G Corporation rose as an opposing power. Lee owned a large portion of stock in the G Corporation and their sudden exercise of military force concerned him greatly. He secretly arranged an investigation into the changes that had occurred within the G Corporation and discovered that Kazuya was at the helm, behind the scenes. Upon learning that Kazuya would participate in The King of Iron Fist Tournament 6, Lee used his G Corporation stockholder's complementary ticket to enter the tournament to get closer to Kazuya.
