sir,
Plz refer to the highlighted part of your post.
I am sorry to say that you have proved your credibility and information "zero".
It seems you don't know anything about the world or UNSC or china.
When china was made UNSC member at that time china has more poverty, more internal tensions and border dispute then India. China is the only country in the world with the largest number of border dispute with the all of its neighbors. India only has border dispute with pakistan and china. But, china still has border dispute with Vietnam, Japan, Taiwan, India etc. etc. The UNSC works on democratic principles but china's dictator govt. don't believe in democracy it is a open mockery of so called free and fair world.
If there is any justice in the world the largest democracy in the world, the fourth largest military power, 11th largest economy, most peace loving nation, a country who have so much contributed towards this world must be given UNSC membership.
thanks
