On 7 September 1993, China and India signed an accord to reduce tensions along their border and to respect the LAC. During November 1996, China and India agreed to delimit the LAC and institute confidence-building measures (CBMs) along the frontier. The agreement pledged nonaggression, prior notification of large troop movements, a 10-km no-fly zone for combat aircraft, and exchange of maps to resolve disagreements about the precise location of the LAC. In August 1997 the sides ratified the CBM agreement.
