Sony plans to introduce its Web-surfing Google TV in nations other than the U.S. but they may have to wait more than a year, especially in China, a senior executive said Thursday.

Sony's Web-linked TV sets, developed with Google Inc., the Internet company based in Mountain View, Calif., went on sale last week in the U.S., with recommended retail prices from $600 to $1,400.

Yoshihisa Ishida, a senior vice president who oversees the Japanese electronics and entertainment company's TV business, said Google's precarious relations with the Chinese government make the TV's introduction there more challenging than in Japan and Europe.
