Junta chief Gen Prayuth Chan-ocha Friday urged Thais not to spread or share hate-speech and lese majeste comments on social networks.
"All Thai people should help get rid of this kind of speech," Prayuth said during his weekly TV programme.
"Information posted on websites, Facebook, and other online applications can be harmful to the younger generations. We have had conflicts in our society and false information has been frequently shared online. We should refrain from sharing unverified information to avoid incitement."
He said hate speech and false information on social networks could be harmful to the country.
"National security cannot be fostered and the society will be degraded. Tourism will be negatively impacted by this atmosphere of hatred," the junta chief explained.
