BEIJING - Chinese police have seized 37 people suspected of printing counterfeit RMB, confiscating bank notes totaling 210 million yuan ($33.4 million), the Ministry of Public Security revealed on Tuesday.

Police in south China's Guangdong Province also captured a number of pieces of equipment including the fake money film source and money printer after they busted a major underground den making fake cash, according to the ministry's news center.

The police cracked a money-counterfeiting case last year, in which they gained clues to destroy the key group involved in forging the money, the ministry said.

The ministry added that it will continue the crackdown on money copying nationwide.
