I am not saying India and China are enemies. There are no friends or enemies on the international scene. I personally maintain favorable disposition towards China due to my Buddhist leanings even though Buddhist Dharma has been pretty much sidelined in China.
I would like to point out that Tibet was an internationally recognized independent country as well just like Pakistan is today. As a matter of fact, both India and China had diplomatic missions in Tibet. China changed the independent status of Tibet by force using the very historical context you are downplaying with respect to Pakistan.
Who recognized Tibet as a country in the whole international community?
Throughout the
Kuomintang years, no country gave Tibet
diplomatic recognition.

In 1950 after the People's Liberation Army entered Tibet, Indian leader
Jawaharlal Nehru stated that his country would continue the British policy with regards to Tibet in considering it to be outwardly part of China but internally autonomous.

The
Provisional Constitution of the Republic of China (1912) stipulated that Tibet was a province of the Republic of China. Provisions concerning Tibet in the Constitution of the Republic of China promulgated later all stress the inseparability of Tibet from Chinese territory, and the Central Government of China exercise of sovereignty in Tibet.
The
9th Panchen Lama traditionally ruled over one-third of Tibet. On 1February 1925, the Panchen Lama attended the preparatory session of the "National Reconstruction Meeting" (
Shanhou huiyi) intended to identify ways and means of unifying the Chinese nation, and gave a speech about achieving the unification of five nationalities, including Tibetans, Mongolians and Han Chinese. In 1933, he called upon the Mongols to embrace national unity and to obey the Chinese Government to resist Japanese invasion. In February 1935 the Chinese government appointed Panchen Lama "Special Cultural Commissioner for the Western Regions" and assigned him 500 Chinese troops. He spent much of his time teaching and preaching Buddhist doctrines - including the principles of unity and pacification for the border regions - extensively in inland China, outside of Tibet, from 1924 until 1December 1937, when he died on his way back to Tibet under the protection of Chinese troops.
