A Japan-China summit could be in the works, but Tokyo is waiting for Beijing to move forward on negotiations, reappointed Foreign Minister Taro Aso said Wednesday.

"We have thrown (the ball into their court)," Aso told The Japan Times, saying Beijing, too, must believe talks should be arranged promptly.

Efforts were being made to hold bilateral talks before a meeting of the Association of Southeast Asian Nations in November, Aso said.
