To enter Cambodia today, foreign nationals must have an insurance certificate covering $50,000 of expenses, be screened for COVID beforehand and have a certificate of non-contamination, written in English, dated less than 72 hours before arrival.
At the airport, these documents are checked and the traveler is screened again at his/her own expense ($100). The traveler is then taken to a hotel to await the results. If all the passengers on the flight test negative, they can leave the hotel, but only to undergo a mandatory two-week quarantine, after which a new test is conducted. If a passenger tests positive, this quarantine takes place at the hotel under the supervision of the authorities and at the expense of the traveler.
Since 15 June, foreigners have also been required to pay a deposit of $3,000 to cover the additional costs of quarantine if it is carried out under the supervision of the authorities, as well as the cost of treatment if the visitor were to contract the virus. Even the cost of cremation in the event of death.
