China on Thursday pledged to extend limits on new home purchases to smaller cities as authorities step up efforts to cool the country's red-hot real estate market.
The State Council, or cabinet, said it would tighten existing property restrictions in cities that have seen excessive price rises to push them "back to reasonable levels".
"Now is a critical moment for property curbs. (We) must not swerve or relax the strength of enforcement," the State Council said in a statement after a meeting chaired by Premier Wen Jiabao.
The cabinet also renewed calls for local governments to start work on up to 10 million state-subsidised apartments by the end of November, adding that construction on half of the target had started by the end of June.
China has introduced a range of measures aimed at reducing house prices since late 2009, such as bans on buying second homes in some cities, hiking minimum downpayments and trialling property taxes in Shanghai and Chongqing.
Beijing is worried that very high property prices, along with soaring food costs, could trigger social unrest as first-home buyers struggle to get a foot in the market.
