Page "Riau Islands Province" Paragraph 11

Some level of unity returned in the Riau region for the first time after 150 years, with the creation of the Sijori Growth Triangle in 1989.

But while bringing back some economical wealth to Riau, the Sijori Growth Triangle somewhat further broke the cultural unity within the islands.

With Batam island receiving most of the industrial investments and dramatically developing into a regional industrial center, it attracted hundreds of thousands of non-Malay Indonesian migrants, changing forever the demographic balance in the archipelago.
