Three Chinese workers were swept away and drowned Tuesday while building a hydropower plant in northern Vietnam, local media reported.
Tran Duc Quy, vice chairman of Ha Giang Province, confirmed with Tuoi Tre (Youth) newspaper that a strong current hit four Chinese workers at around 10 p.m. Tuesday at the site of the plant.
Rescuers found one body soon after that and two more on Wednesday. They were aged 31, 35 and 42, according to local media.
The other was injured.
Quy said work at the plant has been suspended for investigation into the accident.
He said final conclusions would be made after forensic tests.
The workers were employed by China's Zhejiang Company, a contractor of the project.
Work on the 38-megawatt plant started in the middle of 2013 and is scheduled to last three years.
The local Thuan Hoa Hydropower Company said the project costs nearly VND1.3 trillion (US$60.8 million) to build.
