Indonesia's president has announced that the country's capital will be moved from overcrowded, sinking, and polluted Jakarta to East Kalimantan province. President Joko Widodo told a news conference Monday the decision to choose the province on the Indonesian side of Borneo island, which is shared with Malaysia and Brunei, has gone through in-depth studies. He said the most ideal site for the new capital will be between Penajam Paser and Kutai Kertanegara districts, the AP reports. Indonesia's decades-long discussion about building a new capital on Borneo inched forward in April when Widodo approved a plan for it to move from Jakarta on Java, the world's most populous island. Jakarta is a sprawling metropolis of 10 million people, or three times that number when counting those living in its greater metropolitan area. (More Indonesia stories.)
