China's largest residential real estate developers are struggling to adjust their product offerings to better compete due to the soaring supply of low-cost housing.

"We are mulling over a plan on how to differentiate our commercial products in areas where affordable housing will also be available," said Xiao Jing, head of the marketing department at Sino-Ocean Land, a Beijing-based, Hong Kong-listed property developer.

"Improving the product quality, and supporting equipment and services are the major measures we will take," Xiao added.
