AbstractAt present the reform of the United Nations has become a focus of concern among the international community. The reform proposal put forward by Secretary General Annan combined dozens of proposals, of which most of them were raised by the Western countries. Annan's proposal aroused striking responses from all the UN members. Some expressed their approval or cautious welcome, while others were not completely satisfied. An even more complicated and uncertain issue which Secretary General Annan did not touch upon in his proposal is the reform of the UN Security Council. Both Germany and Japan regard permanent seats at the UN Security Council a symbol of their status as major political powers so that they have spared no effort in working to this end. And the competition among the developing countries to gain a permanent seat in the Security Council has made the issue even more complicated. Since the reform of the United Nations involves the utmost interests of all countries and regional groupings as well as the best places they can occupy in the world, it will be hard to settle the issue in a short span of time. The reform of the United Nations is an arduous task.To give top priority to the interests of the developing countries as well as to the development of the world has become the primary subject in the reform process.
