Will the international bodies like UN abandon democratic setup in favor of authoritarian if China gets its way?

The UN is useless. There were majority vote against US invasion of Iraq and they disobeyed UN resolution and did it anyway. So it is either UN is useless or the US is a dictator. It is a fact that China has voted against or abstained from almost every military resolution put forward to UN security council while USA voted in favour for almost everyone of them. Look at the facts and ask this question again.

International bodies have been "authoritarian private clubs" of the West since the end of WWII when most countries were suffering badly from the devastation of war. With BRICS emerging as the world's economic power, getting these bodies reformed is just a matter time. Many G8 nations ie Italy, Canada totally misrepresented to be called "G", even South Korea, Taiwan, Hong Kong and Singapore nowadays are economically stronger than these 2 countries.

Your poorly worded question contains so many incorrect assumptions that it is rendered meaningless. China is a permanent member of the United Nations Security Council and well respected participant within the international community. China has the best solution for most problems.

No. China tends to mind its own business and doesn't really care about what ideology the governments in other countries have.

which international bodies?... those who throw bombs in Africa?... China needs none of them...
