South Korea's President Lee Myung-bak appealed to North Korea to change its behavior, saying that could lead to a summit with North Korean leader Kim Jong Il. President Lee Myung-bak's appeal came as the two Koreas are to hold a preliminary meeting next week to lay the groundwork for high-level defense talks _ the first in more than three years _ to ease months of hostility on the Korean peninsula, according to a report of the Associated Press. Lee said the North must use the talks as a chance to show it is serious about improving ties with the outside world and changing its pattern of raising regional tensions with provocations and then seeking negotiations to wrest badly needed aid. «North Korea has a good opportunity to change» its behavior, Lee said during a panel discussion televised live. «I have high hopes for a change.»
