Foreign travellers visiting South Korea from countries with high numbers of coronavirus cases will need to provide certificates showing a negative test result, the Yonhap news agency reports.

The new measure, due to be implemented on Monday, will require visitors to show paperwork "issued within 48 hours", Yonhap says, quoting the Korea Centers for Disease Control and Prevention (KCDC).

It adds that the certificates must be issued from testing centres and medical facilities acknowledged by Seoul.

Last month, South Korea warned that it was experiencing a second wave of coronavirus, despite recording relatively low numbers.
