Business networking site LinkedIn has been blocked in some parts of China. No explanation was given for the move, which LinkedIn is still investigating, according to Reuters. Some users in China claim their access to LinkedIn has been already restored.

The block comes amid a renewed clampdown of the Internet by authorities in Beijing. Shortly before the site went offline, on February 23, Jasmine Z set up the group "Jasmine Voice." The topic quickly turned to discussing a "Jasmine Revolution" in China, referring to the revolutions that took place or are still ongoing in Egypt, Tunisia, Libya, and several other countries.

The problems accessing the site are likely connected to the creation of the LinkedIn group. The Chinese government has already blocked other social networking sites like Twitter and Facebook, so users reportedly turned to LinkedIn.

Over the weekend, a number of pro-democracy demonstrations were held across China. The police made a handful of arrests, and the attempt was not exactly christened a success. An anonymous online statement claiming to be from the organizers wanting to spark a Jasmine Revolution in China has urged people to gather at designated sites every Sunday afternoon.
