A bill on information technology calls on Japan to build "the world's most sophisticated computerized telecommunications network" so that IT powers the nation's economic growth, government sources said Tuesday.

The bill will be submitted to the extraordinary Diet session to be convened Thursday after being endorsed today by the IT Strategy Council, an advisory panel to Prime Minister Yoshiro Mori.

The bill calls on the government to devise a program specifying goals related to predetermined stages of an envisioned IT revolution in Japan and deadlines for achieving the goals.
