The South Korean government has decided to cut the quarantine period for all overseas arrivals from 10 to seven days.
The change will take effect next Friday, February 4.
The Korea Disease Control and Prevention Agency said the move mirrors recent changes to the country's pandemic response system, including a reduced 7-day isolation period for people who are infected with COVID-19 after being fully vaccinated.
Public health officials earlier said the easing of such restrictions is inevitable as they try to prevent an Omicron wave from causing major disruption to public services and the economy by putting huge numbers of people under quarantine.
The KDCA also announced an entry ban on foreign nationals from 11 African countries, including South Africa, will be lifted.
The ban was implemented in late November after South Korea confirmed its first case of Omicron.
