What is unique about the population of Suriname and Guyana?

That about two-thirds (2/3) descend from Asian immigrants and that the cultural background and the linguistic make-up of the majority cannot be considered Latin American are two unique characteristics of the populations of Suriname and Guyana.

Specifically, the strongest colonial influence is British in terms of Guyana and Dutch in terms of Suriname. Despite pockets of Portuguese- and Spanish-speakers along the borders, the official languages therefore are English in Guyana and Dutch in Suriname. Additionally, Asian influences are atypically strong in both countries. During the colonial history of both northern South American countries, Asian immigration was encouraged, largely from India but also especially from Indonesia.
