The change of Chinese leadership in 2012 may affect its policy toward the Korean peninsular. If we research carefully foreign policy line after 1949, we can find correlation between leadership change and foreign policy. Up to now, Jinping Xi is likely to be the top leadership for the next time. Jinping Xi is descended from the Taizidang(太子黨), it's policy preference is tend to lay emphasis on relations with great powers. Because China accomplish to make Xiaokang(小康) by 2020, they have to strive for continuous development and is very likely to succeed the 'peaceful development' that is the existing foreign policy line. The peculiarity of the Korean peninsular to China will be reflected in Chinese policy toward the Korean peninsular during the era of Jinping Xi that will be persist the keynote of former leaderships, i.e. the maintenance of peace and stability in the Korean peninsular, strengthening influence toward the Korean peninsular and denuclearization of the Korean peninsular. But Chinese policy toward the Korean peninsular will be affected very important factors as Chinese status in the international society, Sino-America relations, relations between the South and the North of Korea, an sudden behaviour of the North Korea and the south Korean policy preference of the next administration, etc.
