I just asked them, they don't support Alipay payment. Anyone from China to help?Some may accept alipay as a buyers payment method (I think Sedo does), but, if the seller wants to be paid with alipay - you'll probably need to use China-based marketplace.
Edited: Dan also lists alipay as a payment method for buyers. Would they show this option for payout to China based seller? Maybe. Or, they may be able to arrange this.
