Internet domain company GoDaddy.com said it planned to stop registering domain names in China, joining Google Inc in protesting cyber attacks and censorship in that country.

'We believe that many of the current abuses of the Internet originating in China are due to a lack of enforcement against criminal activities by the Chinese government,' Christine Jones, Go Daddy Group Inc general counsel, told a congressional commission hearing on Wednesday.

She said GoDaddy had repelled dozens of extremely serious attacks that appear to have originated in China in the first three months of 2010.

Jones said GoDaddy, based in Scottsdale, Arizona, would continue to manage .cn domain names of existing customers. 'Our experience has been that China is focused on using the Internet to monitor and control the legitimate activities of its citizens, rather than penalizing those who commit Internet-related crimes,' Jones said.
