Thirty companies have invested $6.62 billion overseas.
Of that $4 billion has been invested by oil and gas giant Petrovietnam.
It is followed by Viettel ($1.5 billion) and Vietnam Rubber Group ($0.77 billion).
Petrovietnam and Viettel account for a majority of the accumulated profit of $2 billion.
The companies have 94 projects overseas that had combined revenues of $9.7 billion last year, up 24% from 2021.
Notable among them were Petrovietnam’s oil and gas project in Russia and Viettel’s telecom services in Cambodia and Laos.
Others have made huge losses, such as a prospecting project by Petrovietnam Exploration Production Corp, a potassium mining project by Vinachem in Laos and Viettel’s telecom operations in Cameroon.
