Economy Indonesia is a mixed economy with many socialist institutions and central planning but with a recent emphasis on deregulation and private enterprise. Indonesia has extensive natural wealth, yet, with a large and rapidly increasing population, it remains a poor country. The staple crop is rice. Once the world's largest rice importer, Indonesia is now nearly self-sufficient. However, the economy's growth is highly dependent on the continuing expansion of nonoil exports.
Japan remains Indonesia's most important customer and supplier of aid.
Rapid growth in the money supply in 1989-90 prompted Jakarta to implement a tight monetary policy in 1991, forcing the private sector to go to foreign banks for investment financing. The growth in off-shore debt prompted Jakarta to limit foreign borrowing beginning in late 1991. Transportation Despite Indonesia's rough terrain and separated commercial centers, transportation is improving. Most of the highways are spread over Sumatra, Sulawesi and Kalimantan, the antiquated railways system is concentrated on Java. A new international airport in Jakarta opened in 1995 .
