Venezuela is worried about people leaving, because starvation and violence. Venezuela Reopens Border With Brazil, Colombia Perimeter Still Closed
The border with Colombia had been closed on the orders of Venezuelan President Nicolás Maduro to prevent 100 Bolivars from entering the country, which he said were being hoarded by “mafias” in the border city of Cúcuta, Colombia.
The border was supposed to be closed for only 72 hours, during which time banknotes were supposed to be delivered to banks and then removed from circulation. However, the border with Colombia has remained closed.
Brazil had to work through diplomatic channels to get their citizens OUT of the country, when Venezuela closed the Brazilian border.
