I know that India–Myanmar–Thailand Trilateral Highway is still under construction and may become operational later this year. However I came to know that it is still possible to cross the India–Myanmar border from Moreh, Manipur on Indian side. Is it safe to plan a road trip to Mandalay, Myanmar from India by crossing the border in Moreh? Is there any security risks involved for an Indian citizen?
Lots of people go to Namphalong for shopping every day without a visa/passport. It is a porous border unlike the Indo-Pak border where even a flying pigeon is shot down some times due to suspicion. I wont recomend doing this , just wanted you to know that hundreds of people do that every day and it will stop one day.
You can cross the border at Moreh into Tamu if you have the required documents.
Security risk? If you are not a Manipuri native you have a security risk on our side of the border too not just in Myanmar. There are lots of insurgents on both sides of the border not just in Myanmar side. Yes there is a security risk there.
There was a trial run for Imphal to Mandalay bus service in Dec 2015 but regular bus service has not started yet.
