This seems to fit the scheme of Paypal to promote their method of paying in South East Asia, since only PP accounts from India, Indonesia, Korea, Malaysia, Philippines, Thailand, Singapore and Vietnam are eligible to join. But then again, there is nothing that witholds you from making a PP account in those countries is there ;) Be fast, I can imagine that this won't be on for a long time. Good luck!!!
