Abstract: The great historical changes constitute a strong motivation for the reform of the UN Security Council. Through the
historical investigation，it is found that the reform of the Security Council has strong impetus on the surface while different intrinsic
motivations and directions of development. In order to break the "old routine"，the reform of the Security Council has been taking a
fascinating tug-of-war，which has become the "new normal" of in-depth game among all parties. The final goal of Security Council
reform is to maintain world peace and development，not to satisfy and balance the interests and power distribution of member states.
Failing to uphold the concept of the community of humanity，a few countries have not used the veto power of the sanctions resolution
correctly and have deviated from the spirit of the United Nations Charter，which resulted in the weakened implementation of the
resolution and impaired authority of the Security Council. Reform should be focused on how to better meet the challenges and threats
facing the international community and improve the overall program from the top-level design perspective. Therefore，China should
grasp the development direction of the expansion of the Security Council，adopt correct countermeasures in the power competition of
the Security Council reform，and contribute Chinese wisdom to build a community of shared future for mankind.

Key words: the concept of human community with a shared future, the reform of the UN Security Council, veto, sanctions
resolution
