Paypal is the best BUT...too bad it is not the number one payment gateway in China. Not all China people familiar or use Paypal. The number one payment gateway in China is Alipay, the sub company owned by Alibaba.com.

The problem is, with Alipay, the china people can pay you, but you can't receive, coz you can't open an account with Alipay, unless you hold a Hong Kong Bank issued Credit card (except for Hang Seng Bank) or China bank issued credit card. Right now, Alipay does not support any foreign credit card.

Thus, i guess the best is still Bank transfer or western union. If you want to be sure that you are not charged any commission from the transfer, use Western Union. Since you are the seller, so it is not an issue for you. But if anyone were to pay overseas sellers, who insist only on Western Union, please think twice.
