A Chinese millionaire has pledged all his wealth, currently estimated at more than £280 million to charity, and is making it his mission to encourage other rich Chinese to be more giving.

Chen Guangbiao, 42, says that his two sons will have to be happy with their spiritual wealth when he dies and that he, and others in China have to be grateful to Chinese society for the economic reforms that made it possible to get rich, and to repay society by devoting energies to helping China and its people.

Mr Guangbiao is also known for flying to disaster zones to personally carry out aid work.
