China investigated 56,000 trademark rights infringement cases in 2010, an increase of 9.78 percent year on year, an official said on Sunday.

During the 11th Five-Year Plan period (2006-2010), a total of 265,000 cases concerning trademark violations had been investigated, an annual average of 53,000 cases, said Fu Shuangjian, vice director of the State Administration for Industry & Commerce.

Fu told a press conference on the sidelines of the national parliamentary session, protecting trademark rights is crucial to carrying out national strategy on intellectual property rights protection, and to promoting innovation.

Fu said China would further clamp down on trademark violations and strengthen supervision over online shopping, targeting fake goods.
