South Korea’s government is planning to further restrict its citizens from accessing, discussing or forwarding North Korean propaganda activity on social-networking services, such as Twitter.

The plans were outlined in the Justice Ministry’s plan for 2011, which was presented on Tuesday, although lacked specifics.

The South already blocks about 30 pro-North Korean websites although never had to worry about social media until Uriminzokkiri launched a Twitter feed earlier this year.

Here’s the full story at Network World.

The moves follows the sinking of the Cheonan and shelling of Yeonpyeong island and comes despite an already tightening grip on South Korean netizens.

According to a report in the Korea Times from September:

The police forced website operators to delete 42,787 pro-North Korean posts on the Internet in the first half of the year, up about 100 times compared to five years ago, according to data released by Rep. Ahn Hyoung-hwan of the governing Grand National Party Thursday.

Under the previous liberal Roh Moo-hyun administration, the number of censored online articles stood only at 1,238 in 2005; 1,388 in 2006; 1,434 in 2007; 1,793 in 2008.
The director of a cyber crime team at the National Police Agency noted that the number has sharply increased after the Lee administration took office in 2008, jumping to 14,430 in 2009.

The Inter-Korea Exchange and Cooperation Act makes it an offense to have contact with North Koreans without first informing the government.
