Anutin said on Saturday (Apr 18) the plan covers Tak Bai and Waeng districts in the far South and is intended to enhance security along the southern frontier with Malaysia.
The project aims to prevent illegal crossings, improve law enforcement efficiency, reduce unrest and build confidence among local communities, reports the Bangkok Post.
Authorities said detailed design and route alignment will be finalised before work begins. Funding for the first phase is expected from the 2026 central budget, with further phases to follow until completion.
Anutin, who is also director of the Internal Security Operations Command (Isoc), said political and military efforts must work in tandem to achieve lasting peace. He stressed the importance of intelligence-led operations and strict law enforcement based on behavioural evidence to bring offenders to justice.
Meanwhile, Fourth Army Area commander Lt Gen Narathip Phoynok visited Buketa Customs House in Waeng district to monitor operations and provide policy guidance.
He was briefed on cross-border movements of people and goods and screening measures against illegal activity. He instructed military, police and administrative officials to coordinate closely with customs officers to strengthen efforts against smuggling, drug trafficking and insurgent movements. Officials said joint patrols and information-sharing will be expanded in high-risk areas.
The commander also commended officers working under harsh conditions and urged them to prioritise public welfare while ensuring transparent and fair border trade to support the local economy.
Government spokeswoman Rachada Dhnadirek said drug suppression ranks high on Anutin’s agenda.
Despite increased arrests of traffickers in southern border provinces, the spread of narcotics - particularly methamphetamine - remains a concern, especially among youth and young women.
She said plans are under way to establish district-level rehabilitation centres by next year, tailored to local conditions and supported by families, religious institutions, schools, local authorities and security agencies.
Meanwhile, authorities have made progress in the investigation into an attempted assassination of Prachachart Party MP for Narathiwat Kamolsak Leewamoh.
Four suspects have been arrested, with efforts continuing to apprehend another suspect.
