The newly installed chief information officer at trouble-plagued Tokyo Stock Exchange Inc. vowed Thursday to improve the computer trading system of Asia's largest bourse to make it more competitive in the global capital market.

The CIO position was created by TSE President Taizo Nishimuro, who took the helm after a series of problems with the exchange's trading system.

"My feeling is that the TSE has been a bit slow to (respond to) the fast changes taking place" in IT business models, Yoshinori Suzuki, 57, who assumed the post the previous day, said at a news conference.
