Major property developers in China are experiencing a surge in sales, despite the government's clampdown on the real estate market.

China Vanke Co. Ltd., for example, reported sales revenue of 14.2 billion yuan ($2.1 billion) in September, skyrocketing 160.1 percent from one year ago. Poly Real Estate Group Co. Ltd.'s sales stood at 19.7 billion yuan ($2.9 billion) from July to September, compared with 20.8 billion yuan ($3.1 billion) for the first half of this year.

Sales rebounded as pent-up demand was released after several months of gloom, said a report by the Shanghai-based Centaline Property Research Center. In addition, property developers have strengthened house supplies as well as promotional offers, it said.

But continued price surges are less likely as policymakers keep their feet on the brakes to rein in speculation, said Nie Meisheng, Director of the China Real Estate Chamber of Commerce.

In late September, the government announced it would suspend bank loans for third-home purchases. In addition, all first-home buyers will have to pay at least a 30-percent down payment, up from a previous 20-percent requirement. Prior to this, the Ministry of Land and Resources said property developers that haven't broken ground on a site within a year of acquiring the land will be banned from bidding on new sites.
