Several western news agencies banned as "hostile" by the Chinese government were unexpectedly accessible on Thursday, according to Reuters.
The suddenly available sites included the news agency's own, along with those of CNN and the Washington Post.
No explanation was offered by the Chinese government, but it represents a major departure for the regime which had recently encouraged cyber cafe owners to shop surfers trying to access "hostile" western news sites, which can still be found through proxy servers.
Foreign sites have been opened sporadically in the past, but many news sites, including that of the BBC, still remain inaccessible.
