Following record sales last year, Vietnam's housing market has been slowing down, causing oversupply concerns.
The Ministry of Construction has urged local governments, especially Hanoi and Ho Chi Minh City, to take cautions before licensing new residential projects to avoid possible oversupplies, the government website reported on Tuesday.
Local authorities need to review local housing demands and take measures to improve the market's transparency, it said, citing the ministry's order.
The ministry made the move amid reports that apartment sales in Vietnam have been falling.
New figures released by CBRE Vietnam showed 10,107 units were launched in Ho Chi Minh City in the second quarter, up 20 percent from the first quarter. But sales dropped by 35 percent to 5,887 units.
In Hanoi, 6,100 new units were launched in the past three months, a quarter-on-quarter increase of 19 percent. Although the city enjoyed a quarter-on-quarter rise of 20 percent in sales to 4,806 units, it was a decrease of 7.2 percent year-on-year, the company said.
Vietnam's gross domestic product grew 5.52 percent in the first half year, compared to the expansion 6.28 percent recorded in the same period last year, according to official data.
