Under the flight restrictions, Mr. Desclaux could face up to three months in prison. The law restricting the importing of drones carries a potential sentence of up to three years.
Some critics say the rules should be more widely advertised to visitors, who may be unaware of them.
“In some places in Myanmar, you can’t fly drones, but the country should have put up notices,” said Ye Tun Aung, who sells drones in Mandalay, adding that the country’s airports do not have sufficient warnings about the prohibition on bringing in drones.
A small sign on the gate to Myanmar’s Parliament where Mr. Desclaux was arrested explains that drones are banned there, but it is in the Burmese language, with only the word “drone” in English.
In 2017, two foreign journalists, a Burmese journalist and their driver were arrested while flying a drone in Naypyidaw.
