is blocked in Laos, although I do not believe this has been initiated by the Lao government. Lao Internet Service Providers (ISPs) access the internet via Thai ISPs. Thailand has blocked youtube due to videos being shown that were thought to be offensive to their King. Offending the King is a heinous crime in Thailand. His revered status is probably more so than the British royals, even at their height of popularity. A Swiss man was sentenced to 10 years jail, though later pardoned by the King, for painting graffiti on portraits of the King while in a drunken state.

Apparently very little internet filtering takes place in Laos, apart from the odd pornographic site. Other than I have not encountered any internet censorship issues.
