Beware of accessing Paypal while in Myanmar, even to pay for things back home. You may find your account gets limited, and that it will take a lot of effort and faffing around with photo ID / proof of address for it to be reinstated.
I assume you take the same risk if using Paypal while outside Myanmar to pay Myanmar- based companies .If anything, I'd guess this would be more likely to cause your account to be limited since someone in Myanmar is actually benefitting from the transaction.
I appreciate that Western governments want to keep the Myanmar regime under pressure, but responsible tourism is now encouraged. Surely Paypal could limit such draconian action to evidence of a pattern of use in Burma rather than a single, low value transaction ? Even better, when they spot that you've connected from Myanmar, they could warn you that your account will be limited if you continue !
Thanks Paypal !
