The first floor of a shopping mall in Ho Chi Minh City's new Phu My Hung urban area collapsed during construction Wednesday morning.
Rescuers said after a four-hour search that there were no casualties after 200 square meters of concrete floor at the Crescent Commercial Center collapsed, damaging the basement.
The center, invested in by the Phy My Hung Joint Stock Company, was being constructed by the China State Construction Energy Corp.
Work at the center, expected to comprise of six floors and three basements, started in July last year.
Local police and the city Department of Construction are investigating the cause of the collapse, but officials suspect the scaffolding was too weak.
In late 2008, around 600 square meters of concrete floor at another construction invested in by the same company also collapsed, killing one woman, leaving another missing and 14 others injured.
