In her address to a joint session of the U.S. Congress, delivered in English, President Park Geun-hye proposed that a peace park be established inside the Korean demilitarized zone (DMZ). She told the assembled members of congress, "60 years ago, a stretch of earth bisecting the Korean Peninsula was cleared of arms. Today, that demilitarized zone drawn to prevent armed collision is the most militarized place on the planet. And the standoff around the DMZ has the potential to endanger global peace. We must defuse that danger. Not just South and North Korea. The world must also get involved. The demilitarized zone must live up to its name, a zone that strengthens the peace not undermines it. It is with this vision in mind that I hope to work toward an international park inside the DMZ. It will be a park that sends a message of peace to all of humanity. This could be pursued in parallel with my Trust-building Process. There, I believe we can start to grow peace -- to grow trust. It would be a zone of peace bringing together not just Koreans separated by a military line, but also the citizens of the world. I call on America and the global community to join us in seeking the promise of a new day."

The enlarged area of the proposed peace park on the eastern side of the Korean peninsula encompasses northern and southern reaches of Gangwon province, the only province in Korea that is divided by the DMZ.
