France said on Thursday it failed to understand why it was exempt from a new rule allowing fully-vaccinated European Union citizens to enter England without having to quarantine.

From next week, travellers fully jabbed with a vaccine approved by the US Food and Drug Administration or the European Medicines Agency will be able to travel from any country on the British government's "amber" traffic light list without having to self-isolate at home for 10 days, the UK government said Wednesday. Arrivals from France are the only exception.

"This decision is discriminatory towards French people," said French European Affairs Minister Clement Beaune.

"It is excessive and makes no sense in terms of health policy," he told the LCI TV channel, adding that "it has no foundation in science".

The UK singled out France due to the government's concern over the "persistent presence" of the Beta variant, which is believed to be more resistant to vaccines.

But Beaune said the Delta strain accounted for fewer than 5% of COVID cases in France, and mostly occurred in overseas territories from where relatively few people travelled to the UK.

Beaune also said he regretted that travellers from the EU could still not enter the United States, even though American tourists can easily come to EU countries so long as they are vaccinated or have a negative COVID test.

"We should have kept reciprocity as a trump card up our sleeves at the European level," he said. "Perhaps Europe overall should have been tougher in the negotiations."

France on Wednesday reported just under 28,000 new COVID cases for the previous 24 hours and 40 new deaths from the virus.

A total of 111,768 people have died from COVID in France, according to health authorities.
