On 20 November 2016, residents of Gran Chaco Province in south-east Bolivia voted by popular referendum to approve a statute that established Gran Chaco as Bolivia's first autonomous region. This article examines regional autonomy in the Chaco as an example of how identities, territory and political power are being remapped at the intersection of an extractivist development model and competing visions of a plurinational state. I chart how regional autonomy, an elite-led project centred on demands for a fixed share of departmental gas royalties, has been institutionalised under the framework of plurinationalism and used to bolster central state power in this gas-rich region. The article considers the historical evolution of this regionalist project, its intersection with broader processes of state formation under the Movimiento al Socialismo (Movement towards Socialism, MAS) government and its implications for the Chaco's Indigenous peoples, who have achieved significant representation within the regional assembly while seeing their own visions of territorial autonomy sidelined by an extractivist development agenda.

In the last two decades, the concept of plurinationalism has appeared in discussions about nationalism, statehood and multilevel governance, being formulated as a new state model that accommodates cultural diversity within the liberal state with the aim of solving nationalistic conflicts in countries marked by profound ethnic grievances, mainly in Europe. However, these discussions have paid less attention to the meaning of plurinationalism in ex-colonial contexts, particularly in recent experiences of state transformation in Bolivia and Ecuador, where the role of indigenous peoples in the plurinational project has been crucial. To fill this gap, this article explores the legal and political foundations, challenges and local and international dynamics in the building of the plurinational model in both countries. Under a critical engagement with Third World Approaches to International Law (TWAIL), this article argues that plurinationality from indigenous perspectives departs from multicultural liberal models associated with current European plurinational views, and addresses two challenges: a global political economy of resource extraction, and a racialized state structure working as a barrier to actual plurinational implementation. These limitations explain an intrinsic tension in the Bolivian and Ecuadorian experience: on the one hand, plurinational governments try to unify the people around the ‘national interest’ of developing extractive industries; and on the other hand, they attempt to recognize ethno-political differences that often challenge the transnational exploitation of local resources.

Starting from an understanding that maps of an entire nation-state territory reflect and regulate state projects and expressions of national identity, rather than providing detailed technical information for decision making, this paper examines the national maps of race/ethnicity produced under Ecuador's state-led multiculturalism. Using national-scale cartography as a means to examine contested processes of rearticulating state, citizen and nation, the paper analyses recent transformations in cartography, nation building and geographical knowledge in Ecuador. Directing a critical analysis towards the ways maps of indigenous populations are produced, circulated, authorised and read provides a distinctive lens by which to explore postcolonial questions of belonging, rights and presence. The paper discusses how, despite the emergence of innovative maps, the plurinational project envisaged by indigenous cartographers remains stymied by a series of material, cultural and postcolonial limitations.
