The India–Myanmar barrier is a border barrier that India is constructing to seal its 1,624-kilometre (1,009 mi)-long border with Myanmar. India hopes to curtail cross-border crime, including goods, arms and counterfeit currency smuggling, drug trafficking, and insurgency.
The United Nations Drug Control Programme (UNDCP) and International Narcotics Control Board (INCB) also warned that the region could become a major transit point for illicit drugs because of the poor state of border security facilities.
Indian security forces blamed the porous border for the deaths of 200 security personnel and civilians in militancy-related violence in the region in 2001-2003.
Four Northeast Indian states share the border with Myanmar: Arunachal Pradesh, Nagaland, Mizoram, and Manipur. Both national governments agreed to conduct a joint survey before erecting the fence.
The Indian Home Ministry and its Myanmar counterpart completed the survey within six months and in March 2003 began erecting a fence along the border.
