Works of Chinese origin that have entered the public domain in the U.S. due to certain circumstances (such as publication in noncompliance with U.S. copyright formalities) may have had their U.S. copyright restored under the Uruguay Round Agreements Act (URAA) if the work was under copyright in its country of origin on the date that the URAA took effect in that country. (For the People's Republic of China, the URAA took effect on January 1, 1996. For the Republic of China (ROC), the URAA took effect on January 1, 2002.[1])

This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.


Dialog-warning.svg
Note: This tag applies to scans and photocopies only. For photographs of public domain originals taken from afar, {{PD-Art}} may be applicable. See Commons:When to use the PD-Art tag.
Copyrighted in the U.S. This work is not in the public domain in the United States because its copyright in the U.S. was restored by the URAA as it was still copyrighted in its source country (China) on the URAA date (1 January 1996). In most cases, it is copyrighted in the U.S. until 95 years after the year in which it was initially published (exceptions are works published after 1977; see Commons:Hirtle chart).

If you are the copyright holder of this file, and do not wish to have it hosted on Commons, please contact our designated agent or nominate the file for deletion, explaining the situation.
