Access to the networking site LinkedIn has been restored in China, a day after it was blocked after calls for Middle East-inspired protests in the country.

A spokesman for LinkedIn based in the United States said: “We are seeing indications that access to the LinkedIn service is being restored in China. We will continue to monitor the situation.”

On Thursday, Web users in China could not visit the social networking site. While it was unclear whether the site was blocked due to government censorship, the  disruption followed detentions in China after an overseas Chinese Web site, Boxun, spread a call for demonstrations to protest to the Communist party for democratic change.

LinkedIn, with its relatively small user base of adult professionals, has been accessible in China through the local Internet service, unlike Facebook and other social sites with a much larger number of users. It recently surpassed 1 million users in China.

LinkedIn has been planning for an initial public offering in the United States and is preparing to raise up to $175 million.
