President Donald Trump lauded the DMZ as an impenetrable border on the eve of his visit to the fortified zone – drawing a parallel to his signature domestic political issues.

The president made the comment at the G20 summit in Osaka, after his surprise announcement that he will visit the DMZ – and outreach via Twitter to have a quick meeting with North Korean dictator Kim Jong-un if he is in the country.

'When you talk about a wall when you talk about a border that's what they call a border,' Trump told reporters during comments at the top of a meeting with Saudi Crown Prince Mohammed bin Salman.

Compared the DMZ to the wall he wants to run across the southern U.S. border

'Nobody goes through that border,' Trump said. 'Just about nobody. That's called a real border. We're going there. Going to look at it. That's really a point of interest,' he said.

The DMZ has been heavily fortified for decades since the 1953 Korean War armistice. It has been the site of occasional shootings of defectors as well as accidental confrontations.

Back home, Trump has demanded construction of southern border wall, sending troops to string barbed wire and tapping military funds earmarked for other purposes to replace existing wall.

However congressional Democrats have fought his efforts to construct a steel and concrete wall across the entire southern border.
