In a major win for international law enforcement, China has extradited Zhang, the mastermind behind the $14 billion MBI Group pyramid scheme, from Thailand. Zhang's scheme duped over 10 million people, making it one of the largest of its kind. His capture marks the first successful extradition by China's 'Fox Hunt' task force under a 1999 treaty with Thailand. Zhang's return to China not only signifies a significant achievement in global criminal justice but also shatters the ambitions of pyramid scheme operators worldwide.
