A top Japanese peace envoy will push for fresh peace talks between the government and Tamil Tiger rebels during a visit next week, amid optimism that the deadlock could be broken, an official said Thursday. Yasushi Akashi is to arrive on Oct. 27 for a weeklong visit, five months after he warned that future negotiations will be "difficult and complex." Akashi will meet with representatives of the government and the Tamil Tiger rebels to "discuss the current situation of the peace process," said Japanese Embassy spokesman Hideaki Matsuo.
