After more than two years, Mongolia reopened its air border to resume international passenger flights on 1 June, 2021. However, there was strict rules for international travellers due to coronavirus. For example, tourists must present proof of being vaccinated or having recovered from Covid-19 with a negative test result; and once landed in Mongolia, must undergo 3-7 days of self-quarantine.

On 14 March, 2022, Mongolia removed PCR test certificate requirement for fully vaccinated international arrivals. Furthermore, Travellers now can be able to enter Mongolia without having to quarantine.

The number of tourists visiting Mongolia has increased by about 10 percent a year since 2016 but decreased by 94 percent in the last two years due to the global pandemic. As a result, in 2021, the tourism industry lost USD 583 million.
