I found myself could not access the online banking website of Amazon.ca Visa card.  It has been 3 days, I have not been able to check my transaction history.  Eventually I decided to call the customer service.

To my surprise, I was told that Amazon.ca Visa did not allow customers to use it in Myanmar.  Also the online banking website blocks internet access if it's from Myanmar.

I just couldn't understand the reason.

I asked the representive that what other countries were also sactioned by Amazon.ca Visa.  The answers are:  Cuba, Iran, North Korea, Syria...

As I noticed and mentioned before, there are lots of international involvements in Yangon right now.  Myanmar had started its democratical changes since a couple years ago.  Apparently Amazon.ca Visa's sanction is out-of-date.
