Panama papers: China censors online discussion

China appears to be censoring social media posts on the Panama Papers document leak which has named several members of China's elite, including President Xi Jinping's brother-in-law.

Hundreds of posts on networks such as Sina Weibo and Wechat on the topic have been deleted since Monday morning.

The leaked papers, from Panamanian law firm Mossack Fonseca, reveal how the rich have used tax havens.

They mention Deng Jiagui, who is married to Mr Xi's older sister.

An investigative report by Bloomberg News in 2012 suggested that Deng and his wife had hundreds of millions of dollars in real estate, share holdings and other assets.

There are legitimate ways of using tax havens and offshore companies, although these entities are often used to hide the true owners of assets or avoid paying tax on the money.
