Vietnam aviation authorities denied entry of international visitors due to invalid documents.
The visitors were found carrying fake passports or not holding valid visas.
To reduce the number of passengers being denied entry, aviation authorities have required airlines operating regular international flights to Vietnam to strictly check documents of passengers entering or transiting in Vietnam.
The increased number of passengers denied entry has caused damage to airlines which are mainly responsible for sending them back to the place of departure.
In addition, this also created pressure on Vietnamese airports where refused passengers have to wait for their return flight, triggering potential risks of aviation security and safety.
