South Korea, where 60% of the country's 48 million citizens surf, is to ensure all homes can receive broadband connections by 2005.
The 13.3 trillion won (£6.99bn; $10.9bn) programme will be funded by KT Corp, the country's biggest telecoms firm, and internet service providers, backed by government loans.
The broadband connections will be fast enough to transmit the equivalent of 370 newspaper pages in one second, the Ministry of Information and Communication said.
'Knowledge superpower'
The announcement came as the ministry revealed that the number of South Koreans subscribing to broadband services had topped 10 million.

The number "will serve as an important stepping stone for the country to emerge as an advanced information-communication nation in the 21st century", he added.
The new programme is aimed at taking the number of broadband subscribers to 13.5 million by 2005.
