Cherdkiat Atthakorn, director-general of the Department of Information and the ministry’s spokesperson, on Saturday (April 4) explained that after the ban on entry had been announced on April 2, Royal Thai Embassies and consulates had suspended all channels of registration for issuing letters, and also shut down the ministry’s online registration. 
“In addition, we asked Thais to proceed under the regulations issued in the Emergency Decree by obtaining 'fit to fly' medical certificate issued within 72 hours of the journey,” he said. 
“Those who returned on Friday were able to board the plane because they had already obtained the medical certificate and the letter before the decision banning entry was announced.” 
He added that many embassies had warned returnees that they must undergo 14 days of quarantine in places specified by government agencies. 
“Therefore, the news report stating the ministry had violated the prime minister’s orders is not true,” he added.
