Vietnam will host its first Formula 1 grand prix in April 2020.
The south-east Asian country has agreed a "multi-year" deal to stage a race on the streets of the capital Hanoi.
The proposed Hanoi track, which features 22 turns over its 5.565km length, will become F1's fourth street race, along with Monaco, Singapore and Azerbaijan.
It is the first new addition to the calendar under Liberty Media's ownership of the sport.
