Chinese pistols are in demand in the illegal small arms market in India because they are easy to get and cheaper. This creates a major problem for the states of Bihar, Uttar Pradesh, Jharkhand, Chhattisgarh, Orissa, Maharashtra, West Bengal, Karnataka and Andhra Pradesh. These states are affected by Naxalism. Naxalites are groups of Communist guerrilla fighters in India. (Guerrilla fighters are civilians who attack a regular army.) Many Chinese pistols, AK-47s, and M-16 rifles are smuggled into India through the border between India and Nepal. These weapons are then used by the Naxalites, who have ties to Maoists in Nepal.
