Campaigning for Indonesia’s presidential election officially began Sunday with the two contenders releasing white doves and vowing a peaceful race as concerns simmer the campaign will sharpen religious and ethnic divide, the Associated Press reports. The main opposition has outlined a platform that includes a shake-up of labor laws and measures aimed at boosting domestic and foreign investment. Sandiaga Uno, the running mate to former general Prabowo Subianto, said the incumbent had been too slow to respond to pressures on the rupiah. One of the measures under consideration is to offer tax incentives to businesses for converting their US dollar holdings into rupiah, said a government source quoted by The Straits Times.
