In reaction to the governments economic policies, Thaksin Shinawatras Thai Rak Thai Party won a landslide victory over Leekpais Democrat Party (Thailand) in the Thai general election, 2001 and took office in February 2001.

His policy was later called Thaksinomics. During Thaksins first term, Thailands economy regained momentum and the country paid its IMF debt by July 2003 (two years ahead of schedule). Despite criticism of Thaksinomics, Thaksins party won another landslide victory over the Democrat Party in the Thai general election, 2005.
