These are still unknown. We don't even know the border would be opened today. They just open as they want without any announcement.
As far as I know we are now passing the border with temporary border pass that allow to stay in Mae Sot up to 7 days. Maybe it is opened for border trade and for us to return home. I think it is not for tourism and border bounce because it is still not safe around Myawaddy and they may not let the foreigners to enter.
