Why Google Play Store only allows free apps in Myanmar? I am an Android developer and noticed that my apps can not be sold in Myanmar (and other countries) - the country appears in the list but with a strikethrough formatting.

I found a post on XDA forum asking the same. 

Does Google enforce an export restriction of any kind?
Burma or Myanmar had been sanctioned since 1997 by the U.S. due to the political system. The U.S. plans on lifting the sanctions  starting 2013 because Myanmar began to allow democratic elections (Source: Wikipedia). Not all sanctions have been lifted, yet but Google plans on expanding to Myanmar in the future.

From qz.com here:


  "Google Play… and Google Wallet? The Google Play store, the app store
  for Android phones, has been blocked in Myanmar because of
  international sanctions that restrict payments to the country.
  Instead, locals use pirate app stores, which work with their
  jailbroken phones. Google plans to open the Google Play store in the
  near future, and already the country’s app developers report
  restrictions are coming down."


From the US Treasory Department sanction document:


  "With certain exceptions, U.S. persons (both individuals and entities)
  are prohibited from transferring, paying, exporting, withdrawing, or
  otherwise dealing in the property and interests in property of an
  individual or entity on OFAC’s list of Specially Designated Nationals
  and Blocked Persons (“SDN List”), including those listed in the Annex
  to E.O. 13310, E.O. 13448, and E.O. 13464, or determined by the
  Secretary of the Treasury [...]"
