In the past 20 years，while the relationship between China and ROK developed quickly，it also faced the endless problems and obstacles because of the dualism inner structure. On the one hand，the common political，security，economic and cultural interests promoted the rapid development of relations between the two countries；on the other hand，the three internal structural contradictions will hinder the further development of the relations between the two countries. Therefore，the construction of the strategic partnership relations between China and ROK can’t copy the existing construction mode of bilateral relations simply，this kind of partnership relations should be deepened gradually rather than one step reaches the designated position. The two countries should follow this course，i.e. from easy to difficult construction mode，and with the aid of common interests existed between two countries，overcome the three internal structural contradictions and realize the strategic cooperative partnership on a case-by-case basis.
