From the Korean Times:
The copyright period for royalty payments will be extended to 70 years from the current 50 years after the original copyright holder dies, as a step to meet the requirements of the “provisional” free trade agreement (FTA) between South Korea and the United States.
At a Cabinet meeting President Roh Moo-hyun chaired Tuesday, the government passed this and other revisions on copyright protection.
Under the revision book publishers and entertainment-related businesses will be required to pay royalties 20 years longer than is currently required.
