North Korea's powerful National Defense Commission issued a hard-line statement on Friday, threatening not to deal with South Korea's Lee Myung-bak government and ruling out any policy changes, as Yonhap reported. The statement, issued just after the North's new leader Kim Jong-un took power from his deceased father Kim Jong-il during the communist nation's mourning period, seems to represent Pyongyang's future policy stance toward the South. In an apparent move to foster a better relationship with the North's new leadership, President Lee said last week that South Korea has no hostility toward the North and expressed sympathy to the people of North Korea over Kim's death.
