China and India should maintain the momentum of high-level exchanges, China's Vice President Han Zheng told India's National Security Advisor Adjit Doval in Beijing on Wednesday, state media Xinhua reported.

China and India agreed on Wednesday to work on easing their long-running border dispute, as the two Asian giants resumed a formal high-level dialogue for the first time in five years.

The meeting is part of a diplomatic mechanism that was halted after deadly clashes broke out along the Himalayan frontier five years ago.
