The bodies of three boys aged between 7 and 10 were found in a river in the southern central province of Ninh Thuan on Sunday.
On Friday afternoon, Dao Vinh Hung, Le Van Khanh, both 10, and Nguyen Van Bi, 7, went to the Dinh River in the province's Phan Rang-Thap Cham City to bathe.
Their families started looking for them after it turned dark and the boys had not returned home.
They found the boy's clothes on the banks of the river.
After searching for the children the whole night, they sought help from local soldiers who recovered the three bodies from the river on Sunday afternoon.
Around 3,500 children drowned last year in Vietnam.
A report released last month by UNICEF states that drowning is a leading killer of children across parts of Asia. The report surveyed four countries (Bangladesh, Cambodia, Vietnam and Thailand), together with two provinces in China (Beijing and Jiangxi).
