South Korea's President called Monday for cooperation with North Korea and pledged limited humanitarian support for suffering North Koreans as the two nations try to pursue dialogue. Lee Myung-bak made the call in a speech celebrating the Korean peninsula's liberation. The call follows tentative diplomatic talks among officials from the United States, North Korea and South Korea meant to restart international negotiations to persuade Pyongyang to abandon its nuclear weapons ambitions. Lee said Koreans long for reunification, despite the bitter history of the peninsula, according to a report of the Associated Press. "South and North Korea have lived in an age of confrontation for the last 60 years," Lee said in the nationally televised speech. "Now we must leap beyond that age and live in an age of peace and cooperation."
