Beijing is a crucial player in the country's economic growth but increasingly unpopular with voters. Indonesia's economy is South East Asia's largest. It has a population of 250 million and an average annual growth rate of about 5%. By 2050 it is expected to be the fourth largest economy in the world, after China, India and the United States, according to PwC . But analysts routinely say that Indonesia isn't punching its weight, because it's been plagued by decades of under-investment in infrastructure, as well as suffering from corruption and red tape.So, for the 193 million going to the polls next week to choose their next president, economic growth is a key election issue.
