Rwanda's economy has grown rapidly under Kagame's presidency, with per-capita gross domestic product (purchasing power parity) estimated at $1,592 in 2013, compared with $567 in 2000. Annual growth between 2004 and 2010 averaged per year. Kagame's economic policy is based on liberalising the economy, reducing red tape for businesses, and transforming the country from an agricultural to a knowledge-based economy. Kagame has stated that he believes Rwanda can emulate the economic development of Singapore since 1960, and achieving middle income country status is one of the central goals of the Vision 2020 programme. Kagame's economic policy has been praised by many foreign donors and investors, including Bill Clinton and Starbucks chairman Howard Schultz. The country is also recognized internationally for its effective institutions and low levels of corruption.
