This article argues that although most Caribbean States have in the last 60 years ascended to statehood, colonialism continues to exist in new and variable forms. It relies upon the concept of ‘coloniality’ as advanced by Schneiderman to contend that the international investment law regime, whose history and evolution is rooted in colonialism, relentlessly pursues the economic interests of foreign investors and capital-exporting countries. It draws important connections between historic colonialism and the contemporary regime for the protection of foreign direct investment by situating the Caribbean's experience in the light of the rationales, tropes and methods arising in the past which endure in investment law's domains, as advanced by Schneiderman in his new book, Investment Law's Alibis, namely (a) profitability and privilege; (b) a discourse of improvement; (c) distrust of local self-rule; and (d) construction of legal enclaves. It is argued that each of these features of colonial rule, from a Caribbean perspective, is inscribed in the discourse and practices of the international investment law regime.
