The Office of Industrial Economics (OIE) advised garment manufacturers to make quality products to gain from rivals like China and Vietnam, who make low cost products.
The world famous Thai quality provides its garments the advantage over their rivals in the export market, said Atchaka Brimble, OIE's Director General.
Depending on the exporters' commitments to buyers in Southeast Asia and the rest of the world, there are indications that industry will expand, Atchaka said.
It will partly happen due to free trade agreements which the government has signed with a number of trading partners, Atchaka added.
Thailand now stands as the top exporter of garments to Asian markets, she said.
Exports rose 5.4 percent with revenues of $6.11 billion during the first 11 months, compared to previous year, said Atchaka.
Export to America totaled $1.93 billion from January to November last year, for EU it was valued at $1.92 billion and Japan was $382 million.
Cotton textiles domestic production dropped 6.9 percent compared to 2004 due to low-cost imports.
Exports of cotton textiles too, registered a fall 8.8 percent, whereas exports of knitted products rose two percent and crocheted went up to 8.9 percent.
