Chinese biggest property developer China Vanke Co., Ltd. announced Wednesday to sign a deal to invest 3 billion yuan (436 million U.S. dollar) in Lianjia, the second biggest real estate agency in China, with no clear proportion of shares Vanke will hold. 

The Vanke's investment may be driven by the changes in the property market, second-hand housing trade becoming the main deal type in the market. 

Early in this year, another property developer Sunac China Holdings Ltd. has acquired a 6.25% stake in Lianjia at 2.6 billion (375 million U.S. dollar). It is unsure if Vanke is able to acquire more stake than Sunac.
