People arriving in France from the UK will have to self-isolate for 14 days from 8 June, the French government has announced.
It comes after Home Secretary Priti Patel revealed quarantine plans for visitors to the UK from the same date.
France said it would impose reciprocal measures for any European country enforcing a quarantine.
Travellers arriving in France from Spain by plane will also be asked to go into quarantine from Monday.
Speaking at Friday’s Downing Street briefing, Ms Patel said travellers to the UK will need to tell the government where they will quarantine, and face enforcement through random spot checks and £1,000 fines in England if they do not comply.
She said the measure would “reduce the risk of cases crossing our border”.
Lorry drivers, seasonal farm workers, and coronavirus medics will be exempt.
The requirement will also not apply to those travelling from the Republic of Ireland, the Channel Islands and the Isle of Man.
