The order was issued by the Ranong Provincial Administrative Organisation (PAO) after the government announced price guarantees for rubber to help support farmers.
The price-guarantee policy, announced earlier this year, has led to concerns that smugglers are importing cheap rubber from Myanmar to sell in Thailand.
The PAO has deployed additional troops and police to its maritime border. They have been ordered to increase patrols and inspections targeting smuggling.
The PAO is also working with Myanmar’s military regime to crack down on smuggling. The two governments have agreed to share information and cooperate in joint anti-smuggling operations.
