Thailand ordered its ports on Tuesday to keep a close watch out for rogue "elephant pants" being imported to the kingdom, as Bangkok trumpeted its copyright claim to the popular pachyderm print.
The thin cotton trousers have long been a staple of European backpackers travelling through Southeast Asia.
In recent months, they have become an unexpected hit with young Thais.
But a jumbo influx of cheap Chinese-made pants has sparked concern over foreign imports edging out local manufacturers, and caught officials' attention.
"We have ordered the surveillance of elephant pants in all ports," Deputy Prime Minister Phumtham Wechayachai told reporters on Tuesday.
Phumtham, who is also commerce minister, said the elephant design that stomps across the ubiquitous trousers was copyrighted.
"If we allow foreign producers to produce it, it might impact the local Thai products," he said, warning of the inferior quality of some imports.
"Thai products are standardised. Some (imported) products are easily torn after using them a couple of times," he said.
While the pants are sold from market stalls for as little as 150 baht ($4), high-end retailers have also picked up on the trend and some flog high-fashion designs for as much as $30.
Phumtham's remarks come after Thai Prime Minister Srettha Thavisin was asked about the cheap Chinese-made pants dominating the local market.
