India and China are good friends.Our friendship exist not only from Modern Age but from Old Ages :the Kings Rule time when a South Indian King (Cheran) want to build a Siva temple he appointed a Chinese Archetect and his image is also carved in one of the Kopuram(Top Part) of the temple.This is also present in Bradeshwara Temple.Regarding Arunachal Pradesh it belongs to India and the roots are clear.Same with Indian Borders with China.India is a friend to Tibet and we respect Saint Dalilama.Tibet People are welcome in India as per Indian Rules and Regulations.India does not have much of link with Tibet,but Tibet has its right to be a seperate country.India and Tiwan are connected by Diplomatic Authorities only.We never had much intrest in others bitterness.Regarding China and Pakistan Trade is not concerned with India,But Defence Relations are not wise as it directly deals with Heavier Arms Race(Nukes,Baby Nukes and Chemical Wepons).China and India should grow together to create better economies as Western,European and Middle East Countries have already been fully deveoloped and has a strong global economy.This is the only way we can become better Asian Developed Countries.
