gradual lifting of borders has been proposed by the EU's executive in an attempt to kick-start a tourist industry hit hard by the coronavirus pandemic.
"Our message is we will have a tourist season this summer," said economic affairs commissioner Paolo Gentiloni, "even if it's with security measures and limitations."
Borders closed across the EU, including the border-free Schengen zone.
But states are starting to reopen them.
Austria and Germany have become the latest EU countries to agree to remove travel restrictions.
