In a second deal Greenland will invest 600 million pounds to build apartments on a 3,700 square metre site in London's Canary Wharf financial district, it said.

Macrolink also plans to acquire a piece of land for 300 million yuan in Malaysia's Iskandar economic zone, home to the Legoland theme park. It will also set up a real estate firm in the southeast Asian country for 50 million yuan.
