Pinterest was one of the few social media sites still accessible on Chinese territory, where Twitter, Facebook, Instagram, Tumblr, Google Plus, Snapchat, Line and Telegram have been blocked for some time now.
Other websites censored in China include the Google search engine and the video sharing website YouTube, although many denizens in the country find ways to access the blocked sites.
According to Khaleej Times, Pinterest President Tim Kendall had said last year that the site "isn't a social network" but a "catalogue of ideas" which according to him, explained why it was still allowed in China.
The Western sites were widely used to share content China would deem highly sensitive, like the 1989 crackdown on Tiananmen Square protests, Tibet, or the Dalai Lama.
