Thailand's military government will ask other countries to extradite people suspected of insulting the nation's monarchy following the death of King Bhumibol Adulyadej.
Thailand has entered a year of mourning and sensitivities are running high following the death of the revered king last week after seven decades on the throne.
Criticism of the monarch, the regent or the heir, known by the French term lese majeste, is a crime that carries up to 15 years jail in Thailand.
The junta said it has been tracking six high-profile lese majeste suspects living abroad who have tried to stir up unrest in Thailand and will ask for their extradition.
"We will ask for co-operation, friendship and respect from these countries and we hope they understand all Thais cannot accept these insults," Justice Minister Paiboon Koomchaya told reporters.
Paiboon conceded there were significant legal and diplomatic challenges around seeking the extraditions but he would proceed regardless.
The junta last week urged citizens to report cases of lese majeste to authorities. It has also asked internet service providers to monitor content and block inappropriate material.
Some Thais have taken the matter into their own hands. A series of videos has surfaced online in recent days showing angry mobs accusing people of insulting the monarchy.
In the latest incident, a man in Chonburi province was shown being pushed around by a mob and struck several times on the head. He was later forced to prostrate himself before a portrait of the late king, apologise, and shout "I love the king" while onlookers hurled punches and death threats at him.
On Monday, an elderly woman accused of insulting the monarchy was struck in the face after commuters forced her to leave the bus she was riding on.
