The United States on Monday, April 30 again put Russia and China on its list of countries with the worst records of preventing copyright theft, the U.S. Trade Representative's office said.

According to Reuters, Argentina, Canada and India were also put on "priority watch list," along with Algeria, Chile, Indonesia, Israel, Pakistan, Thailand, Ukraine and Venezuela.

The list carries no threat of sanctions, but hopes to shame governments into cracking down on piracy and updating their copyright laws.
