VIENNA — Austria has announced it will open its borders to most European neighbors beginning June 16 with the exceptions of Spain, Portugal, Sweden and Britain.

Foreign Minister Alexander Schallenberg also said Wednesday that the border with Italy to the south would be open without conditions, but that a travel warning for Austrian citizens is in place for Lombardy. The northern Italian region has been the epicenter of Italy’s epidemic, showing triple-digit growth in daily infections while much of the rest of the country counts a handful or fewer.

While Italy opened its borders on June 3, Austria’s reluctance to open the shared border has been a sore spot between the neighbors, especially as the summer tourism season gets under way.

Austria’s opening means that visitors from 31 countries no longer are required to undergo a two-week quarantine.
