Within the whole Indochinese region, populations of the pygmy slow loris have drastically decreased as a result of military activities, defoliant spraying, logging, and massive off-takes, especially in Vietnam. It has been extirpated in the northern part of this country due to the belief that it is a crop pest. The demand of the pet and the medicinal markets is further aggravating the situation, which is reflected by its abundance in many local markets. This demand has recently increased due to human population growth and improved economic conditions within the region. According to CITES, this activity is considered unsustainable.
