China–India relations, also called Sino-Indo relations or Indian-Chinese relations, refers to the bilateral relationship between China and India. Although the relationship has been cordial, there have been border disputes. The modern relationship began in 1950 when India was among the first countries to end formal ties with the Republic of China (Taiwan) and recognize the People's Republic of China as the legitimate government of Mainland China. China and India are the two most populous countries and fastest growing major economies in the world. Growth in diplomatic and economic influence has increased the significance of their bilateral relationship.
The religion and culture of China are undoubtedly of Hindu origin. At one time in the single province of Loyang there were more than three thousand Indian monks and ten thousand Indian families to impress their national religion and art on Chinese soil.
India conquered and dominated China culturally for 20 centuries without ever having to send a single soldier across her border.
Hu Shih. As quoted in Consolation of Mind (2004) by H. K. Suhas, p. 111
Never before had China seen a religion so rich in Imagery, so beautiful and captivating m ritualism and so bold in cosmological and metaphysical speculations. Like a poor beggar suddenly halting before a magnificent storehouse of precious stones of dazzling brilliancy and splendor, China was overwhelmed, baffled and overjoyed. She begged and borrowed freely from this munificent giver. The first borrowings were chiefly from the religious life of India, in which China's indebtedness to India can never be fully told.
