Guangzhou has long dreamed of being considered an international city - but events last month at a downtown police station were not quite what leaders had in mind.
Furious when they thought a Nigerian clothes trader had died, more than 200 Africans dragged the body to the station in Kuangquan district and started a siege.
For four hours they vented their fury at officers and onlookers, smashed plants and trees, and forced traffic on a busy road to grind to a halt.
The protest, believed to be the first by a group of foreigners anywhere on the mainland, was the boiling over of long-standing frustrations with visa policies among the city's sizeable African community.
Emmanuel Okoro fell from a second-storey window of a market when he attempted to flee a visa check on July 15. His fellow traders filmed him with blood pouring from his head and assumed he was dead, but police later said he was still alive and being treated in the intensive care unit of a local hospital.
The incident was a reminder of the huge challenges that internationalisation will bring Guangzhou.
