Restoring ties with Venezuela is a no-brainer for Colombia's new president

One of Gustavo Petro's first moves after becoming president of Colombia was to restore diplomatic ties with neighboring Venezuela.

Why? Petro says that closing the border between two countries who share the same blood has led to an economic "catastrophe."

What's more, he tells Ian Bremmer in an exclusive interview with GZERO World, globalization at its purest is about trade between neighbors like Colombia and Venezuela, which the previous government destroyed "to the point of stupidity."

Rebuilding ties with the Venezuelans is a priority for Petro, who sees it as an important step toward restoring the human rights of those on both sides of the border.
