Nation's efforts lauded in child porn bust

The largest global campaign against child pornography, in which China played a pivotal role, has been hailed a success.

Operation Angel, launched in April, has led to more than 250 arrests worldwide and blazed a trail in multinational operations, law enforcement officials said.

"Child protection is a global issue," said Yang Shaowen, deputy director of international cooperation for the Ministry of Public Security. "The campaign is a vital step for participating nations in protecting our youth."
