BEIJING - China will continue to build millions of affordable housing units and stick to control measures on the property sector next year, the minister of housing and urban-rural development said Tuesday.

The country plans to start construction on 6 million affordable housing units and complete the construction of 4.6 million units in 2013, Jiang Weixin, the minister, told a national work conference here.

He also urged "unswervingly" carrying forward with property controls.

Differentiated credit and tax policies and purchase restrictions in the sector should continue in order to curb speculative and investment demand on the housing market, Jiang said.

China is building more than 7 million government-subsidized housing units this year as part of its five-year plan to construct 36 million such affordable homes by 2015 in a bid to make housing accessible to low-income families.

Runaway real estate prices have been a significant source of public complaint in recent years, forcing the government to implement a string of policies like bans on third-home purchases and property tax trials to keep prices down since early 2010.

However, the property market has shown signs of warming in recent months, after the central bank twice cut interest rates and banks' reserve requirement ratio to buoy the economy earlier this year.

In November, 53 out of a statistical pool of 70 major cities recorded higher new home prices than a month earlier, according to the National Bureau of Statistics. This was up from 35 in October.
