US winning WTO ruling on China's film barriers

The United States appears to have won a victory against Chinese barriers to imported films, books and recorded music in a preliminary World Trade Organization ruling. A public ruling is expected in coming months. A US victory would mark a significant milestone in Washington's longtime battle against piracy in China, which the United States says costs its film, music and book industries billions of dollars in lost sales every year. However, WTO rulings are often complicated documents, giving both sides grounds to declare victory.
