Sales growth slowed to just 1.3 percent in April, down from 47.8 percent in March, following the government's clamp-down against real estate speculation.

A senior government researcher was quoted as saying last week the curbs on property speculation work to control inflation and could ease social discontent over widening wealth disparity.
