BEIJING, June 23 (Xinhua) -- China has cracked 257 cases and arrested more than 11,500 suspects since it launched a campaign against cross-border gambling and related crimes on Feb. 28.

Police across the country have busted 368 gambling platforms, and found out that more than 229 billion yuan (about 32.3 billion U.S. dollars) was involved in the cases, according to a statement from the Ministry of Public Security.
