The European Union's executive has recommended easing COVID-19 travel restrictions next month to let foreign travellers from more countries enter the bloc, hoping to boost the stricken tourism industry this summer.
Under current restrictions, people from only seven countries, including Australia and Singapore, can enter the EU on holiday, regardless of whether they have been vaccinated but subject to tests or quarantine.
New proposals from the European Commission on Monday, but still requiring approval by the EU's 27 member states, would allow in fully vaccinated foreign citizens and those from countries with a "good epidemiological situation".
EU member states are due to start discussing the proposal on Tuesday and the official hoped it would be approved this month.
Travel restrictions because of COVID-19 have inflicted heavy losses on the tourism industry in the EU, which at times has struggled to agree a common response to the pandemic.
If the new proposals are agreed, specific EU countries would be expected - but not legally obliged - to follow the new joint approach. Greece has already agreed to welcome vaccinated tourists from Israel.
Other measures to support tourism this summer include a central EU register allowing free travel for the bloc's citizens holding a so-called "green certificate" proving they have been vaccinated, have had a negative COVID-19 test or have immunity after recovering.
"The green certificate, for the Luxembourg government is one of the elements that would allow us to get back to normality as fast as possible," Prime Minister Xavier Bettel said in separate comments on Monday.
The Commission recommended allowing people fully inoculated with EU-recognised vaccines to be able to enter from any country, and said other vaccines could be added if they are approved by the World Health Organization (WHO).
The European Medicines Agency has authorised the use of shots by Pfizer, Moderna, Johnson & Johnson and AstraZeneca in the EU.
The WHO has also approved those vaccines for use and is expected to decide on the use of two Chinese vaccines this week. Both agencies are considering Russia's Sputnik V vaccine.
The Commission said reciprocity should be considered when deciding to allow leisure travel from third countries.
To limit the risk of importing new coronavirus variants, the Commission also proposed a new "emergency brake" that would allow the swift introduction of travel restrictions from countries where the health situation deteriorates sharply.
EU countries would review the situation every two weeks.
