GUANGZHOU - Intellectual property authorities in Guangdong province have handled 145 cases in the last two years involving alleged copyright infringement related to the Guangzhou Asian Games.

"A series of regulations played a fundamental role in protecting the Asian Games' intellectual property," Zhu Wanchang, deputy director of the Guangdong intellectual property office, said at a press conference on Tuesday.

To protect property related to the Asian Games, authorities from the central, provincial and city governments issued regulations and carried out enforcement campaigns over the past two years, according to Zhu. For example, the regulation on Asiad copyright protection was passed by the Guangzhou government in November 2008 and took effect in January 2009.
