Riau Archipelago

The Riau Archipelago is the core group of islands within the Riau Islands Province in Indonesia, and located south of Singapore. Before the province of Riau Islands was formed, there was no ambiguity in term, however, in Bahasa Indonesian both the archipelago and islands are referred to as simply "Kepulauan Riau", albeit the province may have the word "Provinsi" preceeding it. The island arch definition predates the province by over 200 years.
