A migrant worker has become the 12th Chinese person to die of bird flu.
China reported its first human death from the virus late last year
The official Xinhua news agency says he died in the central city of Wuhan. It is not clear how he contracted the H5N1 bird flu virus.
The man had been taken to hospital in April after showing symptoms of pneumonia, the agency said.
China reported its first human bird flu death in November. The H5N1 virus has killed more than 100 people worldwide since 2003.
Bird flu has devastated poultry stocks, mostly in Asia. Outbreaks have also recently been reported in Africa and Europe.
Almost all human infections so far are thought to have been caused by direct contact with sick poultry.
The virus cannot pass easily from one person to another but there are fears it could mutate, triggering a global pandemic.
