China has taken measures in legislative, judicial, law-enforcement and education fields to strengthen the protection of intellectual property rights (IPR), Chinese Foreign Minister Li Zhaoxing said Tuesday.

Li made the remark at a press conference held on the sideline of the ongoing annual full session of the National People's Congress, China's top legislature.

He said that in 2005 alone, China's industrial and commercial authorities dealt with more than 39,000 trade mark infringement cases. And Chinese courts heard more than 3,500 IPR-related cases.
