Luxury apartment blocks at the seaside city of Sanya, in China's southern Hainan province.

Ocean Flower Island is a vision of luxury, Chinese-style. A man-made archipelago off the coast of the tropical island of Hainan in the South China Sea, it will boast thousands of apartments, 28 museums and 58 hotels including one which is "7-star level" and another shaped like a European castle.

Gold-painted Mercedes golf carts whisk potential customers to the sales centre for the project, where Chinese developer Evergrande Real Estate is leading construction. Inside the centre, Mr Yu, a 56-year-old owner of a building company who asked not to use his full name, wears a shirt emblazoned with the words "Beverly Hills Polo" and sips green tea. He is keen to buy a 108 sq m apartment on one of the islands, adding to his eight properties elsewhere. "The house will definitely increase in value," he says.
