Flight cancellations and the sanctions levied on Russia have already seriously affected the flow of tourists to Phuket.
About half of the Russian tourists arrived in Phuket on direct flights operated by Aeroflot, Siberia Airlines and Ural Airlines.
Aeroflot has cancelled all flights except those to Belarus from Tuesday, and Siberian Airlines grounded flights on Saturday.
Phuket has welcomed 55,826 tourists since the start of Test & Go on Nov 1 last year.
Since the airlines began cancelling flights tourist arrivals have dropped sharply. Tourists who would have used those airlines must now take inconvenient routes to Phuket via Middle East cities such as Dubai, Abu Dhabi, Doha and Istanbul.
Bhummikitti Raktaengam, President of the Phuket Tourism Association, said 500-600 Russian tourists had been arriving each day. This had largely stopped. With more economic sanctions now coming into force, the impact on tourist arrivals would be even greater.
The number of tourists from Europe would also shrink as their purchasing power was reduced by higher fuel costs.
Mr Bhummikitti said he thought economic sanctions imposed by Europe on Russia would eventually backfire. As a result, there would be even fewer tourists from Europe to Phuket.
