Commies aren't into that free speech thing.
China pledged Friday to impose tougher curbs on foreign artists after pop star Bjork sang in support of Tibetan independence in Shanghai, warning similar actions could lead to them being blacklisted.
"We will further tighten controls on foreign artists performing in China in order to prevent similar cases from happening in the future," the Ministry of Culture said in a statement on its website. "We shall never tolerate any attempt to separate Tibet from China and will no longer welcome any artists who deliberately do this."
A video on the Internet site Youtube shows the Icelandic singer closing out her concert in China's financial hub last Sunday with the song: "Declare Independence", during which she yelled "Tibet" several times.
Communist China has ruled Tibet since 1951, after sending in troops to officially "liberate" the devoutly Buddhist region a year earlier.
