As double-digit growth of the Chinese economy continues, it is natural the country's real estate sector will ride the growth curve.

But that does not mean the government can drag its feet on building more affordable houses for low-income groups.

Thanks to the economy's reliance on investment for growth and accelerated urbanization, the country's real estate investment increased to 721.4 billion yuan ($94 billion) in the first five months this year, rising 27.5 percent over the same period last year. Meanwhile, property prices in 70 of China's large and medium-sized cities last month was up 6.4 percent from a year earlier, faster than the 5.4 percent growth rate in April.
