India’s army chief said the situation along the country’s border with China remains calm but the two nations need to rebuild trust in order to normalize relations.

India and China’s poorly defined Himalayan border has fueled decades of tension between the neighboring countries.

Four years ago, 20 Indian and four Chinese soldiers were killed during border clashes following which both sides stopped patrolling several points on the border in Ladakh to avoid new confrontations, while moving tens of thousands of new troops and military equipment closer to the freezing mountainous region.
