Korean fashion house Kukdong Corporation has become the first Asian clothing giant to join the growing international boycott of Australian wool.

The retail group, which makes and distributes the Pierre Cardin, NafNaf, and Jack&Jill brands in Korea, and manufactures apparel for NafNaf, Fox Racing and other famous names internationally, says it plans to remove all Australian wool from its supply chain.

The move is in protest at the practice of mulesing, in which flesh is removed from lambs' backsides in an attempt to reduce the risk of a maggot infestation called flystrike.

"Our customers demand ethically sourced material, and as a result Kukdong Corporation is committed to eliminating Australian wool from our supply chain completely," said SK Byun, CEO of Kukdong.

"We are looking into suppliers in other countries where mulesing does not happen, and we will look at Australian wool again once mulesing has stopped."

The campaign against the use of wool from mulesed sheep has been led by animal rights group People for the Ethical Treatment of Animals (PETA).

Companies that have already joined the boycott include Abercrombie & Fitch, Timberland, H&M, American Eagle, Columbia Sportswear, and Hugo Boss.

Peta is also against the use of alternative methods of removing skin on lambs' backsides, such as 'clip mulesing,' which will be used by some Australian sheep farmers on products marked as 'nonmulesed.'

It argues humane prevention methods exist - such as breeding sheep who are not susceptible to flystrike - but are not widely used.
