Generally if there is a head of a nation  coming for a visit, this type of wall will be temporarily erected. However, no such visits have been announced, at least not publicly.

The barrier appears to be approximately 10 feet high made from concrete k-rails.
What are the barriers there for, and why aren’t they announcing it?
