The Tourism Minister backs revoking visas of foreigners who cause conflicts, after disputes involving Israelis and locals in Koh Samui and Phuket. He says most cases stem from individual behaviour, not all foreigners, and will be handled case by case. He also says unrest in the far South should not hit the Malaysian market during Malaysia's National Day holiday on Aug 31. For tourism-facing businesses in Samui and Phuket, this is a policy signal only; no new rule or deadline is announced.
