DHAKA -- Prime Minister Yoshiro Mori will undertake a visit to South Asia starting Sunday. His brief itinerary will take him to three capitals in the region -- Dhaka, New Delhi and Islamabad.

In New Delhi and Islamabad, the nuclear-arms stance of the two countries and the flash point of Kashmir will doubtless dominate the agenda.

Economic sanctions and international diplomatic pressures following the explosion of nuclear devices by both India and Pakistan in 1998 have not persuaded either country to subscribe to the nuclear Nonproliferation Treaty or the Comprehensive Test Ban Treaty.
