Cathay Pacific Asia Miles - can I transfer AA miles to Asiamiles?

I have some AA miles which I got when taking Cathy Pacific. It is going to expire in a month, can I transfer them to Asia miles?
What is the cheapest way to do it?

thanks

Yes with massive dilution 10 to 2 via Hilton Honors. Info on www.webflyer.com

Better just to keep you AA miles active, search on AA Forum for ideas.
