Thai authorities have warned that tourist visas could be revoked as they move to protect the country’s tourism image, The Nation newspaper reported.
The warning comes amid reports of inappropriate behaviour by foreign visitors in popular destinations including Pattaya, Koh Samui, Koh Phangan and Phuket.
Tourism and Sports Minister Surasak Phancharoenworakul said Thailand remains open to visitors of all nationalities but expects them to respect Thai laws, local culture and communities.
He said authorities would not ignore misconduct or allow isolated incidents to escalate into wider problems affecting tourism.
"Thailand is ready to welcome every tourist who respects Thai law and culture, but we will not allow the country to become a venue for symbolic expressions of conflicts that have nothing to do with Thailand,” he said.
The government is prepared to co-ordinate with immigration and other agencies to take immediate action, including visa revocation, against foreign tourists considered to be causing serious trouble.
The issue has received particular attention on Koh Samui, where local concerns have been raised about the behaviour of some Israeli tourists.
Authorities in Koh Phangan said 13 foreign tourists had already had their visas revoked in recent weeks for inappropriate activities, highlighting the increasingly tough stance Thailand is taking toward unruly visitors.
Thailand has made clear that its tourism destinations should not be used as venues for political or symbolic activities linked to overseas conflicts.
Asked whether visas issued to visitors from particular countries would be reviewed, Surasak said authorities would consider each case individually.
