Since early 2000s, scholars of international relations have been questioning the Western-centrism of their home discipline and, in a quest for pluralism, have been envisioning ways of conceptualizing the world beyond the West. At the same time, an intellectual movement known as modernity/coloniality research collective has been critically reflecting about modernity and its often-neglected counterpart, coloniality, to resist universalism and to decolonize knowledge. Engaging with the attempts to procure pluralism in the discourse of international relations, the purpose of this article is to question the different perspectives of non-Western international relations from a decolonial angle to identify intellectual projects that could lead to decolonizing the discipline. In its discussion of how decolonial non-Western IR theory is, the article argues that while some perspectives within the subfield openly reject or simply ignore the concerns raised by decolonial thought, others put forward intellectual projects where decolonial arguments resonate. Hence, rather than characterizing the subfield in general terms, the article distinguishes those perspectives that are attentive to the need of generating a true dialog among knowledges and, by so doing, it contributes to critical scholarship within international relations.
