Since the New Year, interactions between China and India at multilateral and bilateral levels have been eye-catching. Beijing and New Delhi have expressed willingness to step up security cooperation and work for common development.

On Thursday, State Councilor Dai Bingguo delivered a letter from newly elected Party chief Xi Jinping to Indian Prime Minister Manmohan Singh. Dai was in India to attend the third meeting between the National Security Advisers of the BRICS countries: Brazil, Russia, India, China and South Africa.

Xi said in his letter that the world has enough space for the common development of China and India, and it needs the two countries to realize common development. China's latest interpretation of Sino-Indian ties, which is full of goodwill, has drawn much media attention in India.
