An amusing video has emerged of a man staging a bizarre protest outside the Chinese embassy in London after the Chinese government banned people from eating bananas 'erotically' online.

The video, which has gone viral on Youtube, shows prankster Phil Watson eating a banana in a sexually suggestive way, right outside the embassy building.

Watson can be seen drizzling some chocolate sauce over the fruit and proceeding to run his mouth over it.

According to state-owned CCTV News, "all of the major platforms - Douyu, Panda.tv, YY, Zhanqi TV, and Huya were under investigation."

"It said that these platforms were accused of hosting content that was too vulgar, violent, or too sexual."
