High Quality Content by WIKIPEDIA articles! The economy of Macau has remained one of the most open in the world since its reversion to China in 1999. Apparel exports and gambling-related tourism are mainstays of the economy. Since Macau has little arable land and few natural resources, it depends on mainland China for most of its food, fresh water, and energy imports. Japan and Hong Kong are the main suppliers of raw materials and capital goods. Although Macau was hit hard by the 1997-98 Asian financial crisis and the global downturn in 2001, its economy grew approximately 13.1% annually on average between 2001 and 2006.
