Why China, the only permanent Asian member of the UN Security Council, wants it to stay that way

When Russia offered its backing to India earlier this month, the support was full throated.

Denis Alipov, the Russian ambassador to India, said New Delhi had a "balanced and independent approach to most topical issues" and warranted becoming a permanent member of the United Nations Security Council.

A few months earlier, Russian President Vladimir Putin had also backed India's bid, saying international laws must reflect the "requirements and demands of today".

India is pushing to get a seat at the table with the council's five permanent members, or P5 - Britain, China, France, Russia and the United States.

Those five represent victor nations of the second world war, and now with Russia behind India's bid, only one - China - remains opposed to admitting the South Asian giant.

Analysts say Beijing is determined to remain the only Asian nation in the exclusive group, and will not be swayed by Moscow's efforts.

They also say that any other efforts to add permanent Security Council members seems wishful thinking, with many challenges, including the difficulty of amending the UN Charter, standing in the way.

Vinay Kaura, an assistant professor at Sardar Patel University of Police, Security and Criminal Justice in India, said China had not been influenced by Russia's consistent support for India, resisting any restructuring of the Security Council that carried the prospect of bringing India into the group.

"China's animosity towards India finds its echo in this debate," he said. "Since China is the only Asian power represented in the UN Security Council, it does not want any other Asian country to share this privilege."

China's ties with India have soured in recent years as tensions at their shared border soared. Both Asian powers have also been competing to represent the developing world.

Kaura said Beijing's opposition had also been apparent in its strategy to downsize and restrict India's strategic influence at both a regional and global level.

While China has said it supported reforms to the UN Security Council, it has stopped short of providing specific proposals. Its key suggestion has been that developing nations should have "a greater say".

Last year, Wang Yi, China's top diplomat, said reform should "increase the representation and voice of developing countries, allowing more small and medium-sized countries to have more opportunities to participate in the decision-making of the council".
