A remarkable characteristic of Indonesia is that the western part of the country has a significantly larger contribution share towards the nation's GDP growth. Java (especially the greater Jakarta area) and Sumatra together contribute more than eighty percent to Indonesia's total GDP. Primary reason for this situation is that western Indonesia is located close to Singapore and Malaysia. Together these three parts have historically functioned as the center of economic activity in Southeast Asia. The eastern part of Indonesia, however, is positioned in a more-or-less economic vacuum.
