India and China have reached a deal on patrolling their disputed Himalayan frontier to resolve a four-year military stand-off, Foreign Secretary Vikram Misri said on Monday, paving the way to normalise political and business ties.

In a significant diplomatic breakthrough four years after the Galwan Valley clash, India and China have reached a patrolling arrangement along the Line of Actual Control.

The agreement, announced by India’s foreign secretary, marks a major thaw four years after bloody clashes between soldiers on the border tanked bilateral relations.
