Senior Indian and Chinese officials are huddled in New Delhi in talks aimed at resolving the long-standing border dispute.
China's special representative Yang Jiechi is in Delhi for talks with National Security Adviser Ajit Doval in the first such discussion since the Narendra Modi government came to power.
The talks are clearly aimed at smoothing the road a little before Prime Minister Modi visits Beijing in May.
The two countries share an ill-defined 4,057km (2,520 miles) border and fought a brief war in 1962; and tension has simmered between the neighbours since then.
In September last year, they were involved in a bitter two-week stand-off near their de facto border in September 2014.
Despite business-oriented bonhomie, tensions have flared up from time to time, and numerous rounds of border talks have been unsuccessful so far. The latest meeting in Delhi is the 18th round of boundary talks.
In September during his visit to India, Chinese President Xi Jinping said he was committed to working with India to maintain "peace and tranquillity".
But commentators suggest China's territorial aggression has become almost ingrained, with the belief that it historically owns most if not all of Asia.
