without opposing views,healthy discussion couldn't be made, so let'dips _view" present his view on this matter,
let us goes to History..
1) In 1842 the Sikhs confederation win Ladeh and part of northern area where ruled by Kasmir Maharaja.
2)In 1846 British defeated Sikhs consequently these areas are transferred to them.
3)In 1862, the Johnson Line indicate 'Akaisin' as part of Bristish India, but Chinese refuse to accept it sent expedition to that area erected 'markers' in the Akaisin outer border.
3)at the start of 19th century the British alarmed with Russion influence in Central Asia temporarily handed the administration ofAksai-chin to Chinese.The newly-created border was known as the MacCartney-MacDonald Line
4)After Russion Revolution Russia's Red revolution, the british again shifted to previous 'Johnson line' Official India Maps shown at the time of Independence is contained Akai-chin within India.
On 1 July 1954, Indian Prime Minister Jawaharlal Nehru definitively stated the Indian position."that Aksai Chin had been part of the Indian Ladakh region for centuries, and that the border (as defined by the Johnson Line) was non-negotiable
5. In the earlier 18 th century Tibet was a free state (although the chinese claim sovereignty. they have no actual control over Tibet .Also the disputed 'Tawang Tract' which is part of Arunanchal Pradesh was at that time by the control of Tibet.It is a trading centre between Tibet and outer world
6.In 1913, the representatives of china ,Great Britain Tibet met in the Simla and agreed for a redrwal of a map,which include Tawang within India.
7.But later the Chinese refuted the treaty saying,that the Tibetan government should not have been allowed to make a such a treaty, rejecting Tibet's claims of independent rule.
When the British left India, they didn't defined the rule of Tibet, but simply stated that both india and china took Joint custody of it.
But China violated the agreement,by invading Tibet and occupied it.

So Tibet is the part of problem.. by giving concession to China that Tibet is part of china, Present position of India is virtually giving Arunanchal Pradesh which include 'Tawang'
Only way to tame the 'chinese dragon is. Recognise 'Tibet' as a free state, so treatise made with tibet are valid now, and india has the strong claim with Akaichin, Kashmir, and Tawang tract...
whether indian leaders has this gut.."
Let me conclude, What Dr, Ambedkar said in this matter in 1954 in parliament
By allowing the Chinese to take possession of Lhasa, the Prime Minister has practically helped them bring their border down to the Indian border... Aggression might well be committed by people who are always in the habit of committing aggression. ”
–B. R. Ambedkar at the Indian Upper House, 1954
