They also say the conference could result in a stronger UN that could help the world maintain stability and promote economic and social development.

"We hope the UN in the 21st century will be an institution that will be stronger, more democratic and more efficient," said Chen Pingchu, vice-president of the UN Association of China in an interview with China Daily.

"Reform is necessary for the UN to make it more efficient, but any result of the reform should reflect the common interests of its member states," said Chen's colleague Zhang Wanhai, the association's deputy director-general.

The September 6-8 summit, which has the theme "the United Nations in the 21st century," has attracted heads of state or government from 152 UN member states.

"This shows the role of the UN is irreplaceable," said Chen.

There was widespread disappointment last year after NATO, circumventing the UN, bombed Yugoslavia in the name of "humanitarian intervention."

After this, some doubted the authority of the UN and even feared the organization, founded 55 years ago, would be jeopardized.

"The principles of the UN Charter are not out of date," stressed Zhang. "Each member state should recommit itself to respect and observe the purposes and principles of the Charter," Zhang said.

The UN is now faced with a different international environment to the one that existed when it was set up, he added.

"Profound changes are taking place in the international community," said Li Baodong, director-general of the Department of International Organizations and Conferences under the Ministry of Foreign Affairs.

But he added: "There are still a number of factors causing instability, such as a Cold War mentality and the belief in power politics."

A number of countries, including China, have in recent years advocated the establishment of a new political and economic world order that emphasizes equity among all countries.

"Concerning major international issues and world affairs, all countries should be entitled to participate in the deliberations and resolutions," said Chen.

Apart from political issues, globalization and technological development are expected to be two major topics discussed at the summit, he said.
