After the military crisis triggered by Yanping Island 2010,both North and South Korea adjusted their internal and external policies under the joint effort of themselves and the international community. They have sent out a series of reconciliation signals and created good environment for their further communication. Although the relationship between North and South Korea still went through ups and downs in 2011,the overall tension is defused and a better situation looms ahead. In consideration of the historical transition and the geographical location of the Korean peninsula,the relationship between North and South Korea not only depends on both of the two parties,but is also influenced by the surrounding major powers. The sudden death of Chairman Kim Jong-Il brought more uncertainty to the future relationship between North and South Korea,while the oncoming general election of the several major powers in 2012 will increase the level of the uncertainty. We calculate that in the upcoming 2012,the relationship between North and South Korea will most probably remain the same as 2011,while uncontrollable variables will still exist at the same time. <<
