China's National Copyright Administration said on June 25 that it will add Apple's App Store, Amazon and Taobao, the country's largest C2C online marketplace, to its copyright supervision plan in this year's campaign against online piracy.

These online platforms will be required to report on their measures for protecting copyrights and handling complaints filed by title holders, according to a statement issued by the administration.

The administration will also extend its supervision to music videos for the first time and make an initial list of 24 major video portals to be supervised.

A four-month campaign against online copyright infringement and piracy was launched in late June.

Statistics from the administration show that from 2005 to 2012, authorities across the country investigated 4,051 cases of online copyright infringement and piracy. Of the total, 299 cases were transferred to judicial authorities for handling.
