The contested 2001 presidential elections in which then-mayor of Antananarivo, Marc Ravalomanana, eventually emerged victorious, caused a seven-month standoff in 2002 between supporters of Ravalomanana and Ratsiraka. The negative economic impact of the political crisis was gradually overcome by Ravalomanana's progressive economic and political policies, which encouraged investments in education and ecotourism, facilitated foreign direct investment, and cultivated trading partnerships both regionally and internationally. National GDP grew at an average rate of 7 percent per year under his administration. In the later half of his second term, Ravalomanana was criticised by domestic and international observers who accused him of increasing authoritarianism and corruption.
