Two borders away
These six countries border a neighbour of Thailand but not Thailand itself, so you cross exactly two borders to reach them by land.
Think you know your neighbours?
Border Chain gives you two countries and you connect them by naming neighbours, one border at a time. A new puzzle every day.
How far are you from Thailand?
On a phone this uses GPS. The calculator opens with Thailand already selected and measures the straight-line distance to its nearest border.
