From everything I read you should be ok. I also read what you did about the conference. It seemed like the confiscations were continuing AFTER the conference was completed. Either the local officials didn't get the memo or they're using it as a pretext for getting tourists' hardware and/or money.Thank you for you comments.
I have only a domestic flight At Danang airport from Saigon.
So if i am not mistakes this will not be an issue.
Am i right?
Also ι have read a report that says that this problem existed at a time when they had a conference in the country. Nothing similar has happened in recent years.
In any case be safe and enjoy your trip to Vietnam!
