Business leaders from Japan and the United States expressed their support Monday for a reduction in Nippon Telegraph and Telephone Corp.'s interconnection charges, a move which they say is essential to information technology-led economic growth.

During the 37th Japan-U.S. Business Conference, Japanese and U.S. business leaders started full-scale discussions on bilateral economic issues ranging from electric commerce and patenting business processes to lowering NTT's interconnection charges.

About 90 business leaders from the two countries took part in the three-day meeting, held in the form of a plenary session and small-group discussions. The conference is expected to issue a joint statement at the end of today's session.
