Earlier this week, South Korean President Lee Myung-Bak announced that his country will suspend all trade with the communist North -- a move that could cost the North up to $200 million a year. This measure will be paired with an appeal to the international community to show its disapproval of the North's actions. China, arguably the nation with the most clout in Pyongyang, has strategically disapproved of the situation without directly blaming North Korea.
