The Belgian foreign ministry has placed certain areas of France on its list of countries to which travel is not possible 'without authorisation'.
The areas listed are Paris and its surrounding suburbs of Seine-Saint-Denis and Val-de-Marne, the Pays-de-la-Loire département of Sarthe, and Hérault, Alpes-Maritimes and Bouches-du-Rhône on the French Riviera.
These areas are all – apart from the Nice département of Alpes-Maritimes – on France's list of 'red zones' where the number of new cases of Covid-19 being reported are high.
French Guiana and Mayotte are also on Belgium's banned list.
The rest of France is on Belgium's 'moderate' list, where travel is possible with conditions.
The list relates only to non-essential travel such as tourism, essential travel from Belgium is still allowed, but with authorisation.
Germany earlier this week imposed compulsory testing an quarantine on all arrivals from the Paris and Marseille areas, which both have high levels of new cases, while the UK has imposed a quarantine on all arrivals from France.
