The number of economic crimes in China increased by ten percent to 36,000 during the first half of 2007, said an official with the Ministry of Public Security on Tuesday.
"A total of 1,247 crimes involved production of fraudulent and shoddy products, up 24.3 percent on the same period of 2006," said ministry spokesman Wu Heping.
China also reported 3,695 financial fraud cases and 558 smuggling cases, up 14.3 percent and 23.7 percent respectively. The number of intellectual property rights piracy cases reached 1,094, up 2.7 percent.
Cases involving fraudulent mobile phone text messages were also on the rise.
"We found some criminals from Taiwan had colluded with those on the mainland to conduct fraud crimes through mobile phone short messages, and most of them were based in southeast China's Fujian Province," Wu said.
Almost every mobile phone user in China has received text messages involving financial fraud, smuggling and pornography. One of the most common is telling the mobile phone owner that his or her bank card has been used and asking for his or her personal information.
Wu said victims of the fraudulent text messages have been found overseas, including the Republic of Korea, southeast Asian countries and Europe. And the criminals' bases have moved from Fujian Province to other places on the mainland.
