Yes, my country blocked some information from North Korea for

As you can see google's case in
wikipedia, Internet censorship of china, china is notorious for its “great firewall of China”.
Since announcing its intent to comply with Internet censorship laws in the People's Republic of China, Google China has been the focus of controversy over what critics view as capitulation to the "Golden Shield Project" (also known as the Great Firewall of China). Because of its self-imposed censorship, whenever people search for interdicted Chinese keywords on a blocked list maintained by the PRC government, google.cn will display the following at the bottom of the page (translated): In accordance with local laws, regulations and policies, part of the search result is not shown.
Google has argued that it can play a role more useful to the cause of free speech by participating in China's IT industry than by refusing to comply and being denied admission to the Chinese market. "While removing search results is inconsistent with Google's mission, providing no information (or a heavily degraded user experience that amounts to no information) is more inconsistent with our mission," a statement said.

The National Police Agency successfully ordered YouTube to remove video
of a television news report alleging the brother of Eo Cheong-soo, the
national police chief, owns a hotel where prostitution commonly takes
place.
An official at
Google’s Korea unit said, “We received an
official statement on May 27 from the NPA’s cyber terrorism
countermeasure team demanding that we delete video footage about a
brother of NPA Commissioner General Eo Cheong-soo, citing defamation.
That evening, we temporarily deleted two pieces of video footage.
The
Internet Protocol addresses for both pieces of video footage are
blocked so users in South Korea can’t access them,” the official said.
The original footage, aired by MBC’s Busan branch on April 23, reported
that the brother of NPA Commissioner General Eo had allegedly managed a
hotel that allowed prostitution.
