Prime Minister Yoshiro Mori said Saturday that he will call on India and Pakistan to sign an international treaty banning nuclear tests while he is on a weeklong tour of South Asian nations.

Mori also told reporters aboard a government jet headed for Dhaka, the first stop on the four-nation tour, that he will urge the two arch-enemies to resume their stalled dialogue in order to ease tensions in the region.

"I would like the two countries to sign the Comprehensive Test Ban Treaty and will strongly urge them to do so during this trip," Mori said.

"I will also appeal for the realization of sustainable peace between India and Pakistan," he said.
