TOKYO, April 17 (Xinhua) -- Tokyo stocks were range bound Tuesday morning as investors both bought on the back of U.S. shares advancing overnight and sold on a halt in the yen's decline against the U.S. dollar amid a cautious mood ahead of a Japan-U.S. summit starting later Tuesday.

The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, shed 3.83 points, or 0.22 percent, at 1,732.39.
