A Chinese man stood trial Thursday in east China's Zhejiang Province for a cross-border online gambling case involving 400 billion yuan (57.8 billion U.S. dollars).

Zhou, 47, was charged with establishing an online casino in June 2012 in Wenzhou, according to Songyang county people's court.

In May 2013, Zhou relocated his company to Vietnam to avoid the Chinese police.

In June 2014, police in Songyang opened an investigation into Zhou's activities. Police discovered that 2.04 million players bought 400 billion yuan worth of game coins. Zhou and his accomplices made 580 million yuan in illegal earnings.

Zhou was arrested in Vietnam and repatriated in April this year.

Eight of his accomplices were sentenced in an earlier case and several are still at large.
