Around 500 million Chinese read animation books or watch cartoons, making China the world's largest animation market, according to experts at a cartoon industry forum held in Qingdao at the weekend.

Fifty-nine percent of animation fans are aged between 14 and 17 and adults account for 30 percent.

But China's cartoon industry is still lagging behind the world leaders, experts said, despite increased government investment in recent years.

"Several hundred schools and universities that offer animation majors have now been set up," said Sun Lijun, head of the animation college of the Beijing Film Academy. "These efforts will help boost China's cartoon industry development."

Chinese animation works have been criticized for their lack of originality and are subject to government controls over their content.

The forum, organized by the central committee of the Communist Youth League of China and the Information Office under the State Council, called for all cartoons to promote "excellent traditional culture and represent the modern spirit".

Foreign cartoons, especially from Japan, are hugely popular with China's 250 million children and American cartoons such as The Simpsons have gained a strong following from young adults,

However, in August, the State Administration of Radio, Film and Television (SARFT), issued a ban on foreign cartoons from prime time television programs.

Zhao Shi, SARFT's deputy director, said that the ban was imposed in response to requests by children and parents to screen domestic cartoons on prime time television.

China produced more than 50,000 minutes of animation by the end of August this year, exceeding the total output last year, and is expected to produce 70,000 minutes of animation by the end of this year.
