"The SIJORI growth triangle is a partnership arrangement between Singapore, Johore (in Malaysia), and Riau (in Indonesia) that combines the competitive strengths of the three areas to make the subregion more attractive to regional and international investors. More specifically, it links the infrastructure, capital, and expertise of Singapore with the natural and labour resources of Johore and Riau."
But the once strong cultural unity of the region with Riau in the heart of it never returned, and the line drawn by the British in 1819 remained, this time marking the divide between three new countries as of 1965: Singapore, the Malaysian federation in the north, and Indonesia in the South.
It is those new countries, however, which created back unity in the Riau world for the first time after 150 years with the creation of the SijoriGrowthTriangle.
But while bringing back some economical wealth to Riau, the SijoriGrowthTriangle somewhat further broke the cultural unity within the islands.
