"We have less tourists, of course, in France, about 30%, 40% less than expected," Bruno Le Maire told CNBC's Dan Murphy on Sunday at the G-20 Finance Ministers and Central Bank Governors' Meetings in Riyadh, Saudi Arabia.
"That's, of course, an important impact for the French economy," he said.
Amid travel bans and trip postponements, demand for air travel has fallen, leading to more than 200,000 flight cancellations.
France is one of the most visited countries in the world. According to the country's Ministry for Europe and Foreign Affairs, 89.4 million visitors toured France in 2018 and tourism accounts for nearly 8% of its gross domestic product.
It also welcomes around 2.7 million Chinese tourists each year, Le Maire said. "It won't be the same, of course, in 2020."
France has reported 12 confirmed cases of the virus and one death, according to a WHO report dated Feb. 22.
