The Asiatic mode of production is a notion that has been the subject of much discussion by both Marxist and non-Marxist commentators. The AMP is the most disputed mode of production outlined in the works of Marx and Engels.[6] Questions regarding the validity of the concept of the AMP were raised in terms of whether or not it corresponds to the reality of certain given societies.[7] Historians have questioned the value of the notion of the AMP as an interpretation of the "facts" of Indian or Chinese history.[8]
