London: Internet search giant Google has said that many of its online services have been blocked in China.
Traffic to its services in China dropped sharply on Friday evening according to an online "Transparency Report" website operated by Google.
Google's search engine and its Gmail web email were among the services affected in China, where the internet company has had a fractious relationship with the authorities.
According to the Guardian, Google's YouTube video service has been inaccessible in China since 2009, while access to other services in China are blocked sporadically.
In 2010 Google relocated its Chinese search engine to Hong Kong after a spat with authorities over censorship and cyber-attacks that Google said originated in China, the paper said.
According to the paper, the services were inaccessible just after the country's once-in-a-decade meeting to transfer power to a new generation of leaders got underway.
