The list has already aroused controversy after sources revealed that the United States - the worst-affected country worldwide by COVID-19 with more than 2.4 million cases, is on the latter list.
The countries whose citizens will have quarantine-free access to the European Union from 1 July include: Algeria, Australia, Canada, Georgia, Japan, New Zealand, Montenegro, Morocco, Rwanda, Serbia, South Korea, Thailand, Tunisia and Uruguay.
China is on the list but only on the condition that European Union citizens are allowed to travel to the country as well.
Restrictions for travel within the European Union and with Schengen countries had already been lifted on June 15, but now citizens from 14 more countries around the world have been labelled safe to be let in.
The commission cleared Algeria, Angola, Egypt, Ethiopia, Mauritius, Morocco, Mozambique, Namibia, Rwanda, South Africa, Tunisia, Uganda and Zambia.
A European briefing last week noted that the US had seen 107 cases per 100,000 people in the previous 14 days, whereas the average across the E.U. was 16 cases per 100,000 people.
The number of confirmed coronavirus cases in the United States has surged over the past week, and President Donald Trump also suspended the entry of all people from Europe's ID check-free travel zone in a decree in March.
Note that earlier this green list contained 54 countries and Ukraine was included in it.
On June 11, the commission presented its recommendation on the reopening of internal Schengen borders on June 15, so that Europeans could travel within the borderless area freely, just as they did pre-pandemic.
A qualified majority of EU countries - at least 55% of the EU countries, representing 65% of the EU population - have signed off on list.
"The criteria to determine the third countries for which the current travel restriction should be lifted cover in particular the epidemiological situation and containment measures, including physical distancing, as well as economic and social considerations", the statement said.
