HONG KONG — Guo Wengui, a Chinese-born billionaire who lives in America, has recently publicized accusations of corruption against family members of top-ranking Chinese Communist Party officials. This week, China’s government asked Interpol to issue a request for his arrest.

On Friday, Facebook suspended Mr. Guo’s account. After Mr. Guo complained publicly, Facebook said the suspension had been a mistake, and his account was restored.

The incident comes in the middle of a full-court press by the Chinese government to push back against the accusations from the eccentric billionaire. It highlights a persistent problem for Facebook, which must manage matters as varied as bad manners and high-stakes political battles on a website with nearly two billion users.

Facebook has been in a protracted and public courtship with China, which blocks the social network but has the world’s largest internet-using population. The New York Times reported last year that Facebook had developed a tool that would let third parties censor the social network as part of its attempt to gain entry into the market.
