The number of Cambodians leaving Thailand has soared to more than 120,000 in recent days, officials say.
Many fear Thailand's new military rulers are about to crack down on migrant workers, which Bangkok denies.
Cambodian authorities are now reportedly preparing to deal with the influx.
The new figure is a significant proportion of the number of Cambodians in Thailand, estimated to be at least 150,000.
