Roh Moo-hyun
South Korea received the highest marks on the Reporters Without Borders Press Freedom Index under his administration. The value of the South Korean won against the US Dollar was the strongest during his administration since 1997. Due to the strong currency, for the first time in history, South Korea became the world's 10th largest economy and exceeded the $20,000 milestone in nominal GDP per capita during his administration.
