Leading garment maker Tack Fat Group International on Wednesday said it plans to increase swimwear production at its plants in Cambodia in a move that will create around 2,500 jobs.

The company said it will invest $6 million in expanding swimwear production at its Cambodian factory fivefold to one million pieces a day in the run-up to the country's entry to the World Trade Organisation.

Chairman Kwok Wing said following the increase in production, swimwear will account for 40 per cent of its total sales compared to the current 30 per cent share.

He said apparel made in Cambodia would benefit from favourable trade terms with the US, Canada and Europe.

Mr Wing also announced plans to move more clothing production to Cambodia as well as increase its workforce in China almost sevenfold to 20,000 over the next few years.
