It is very strange that the article doesn't establish if "mutual consent" was needed to trim shrubs or not. Seems like a core element to contextualize the whole event. I did a little digging but even I cannot figure it out. The JSA was created via the Military Armistice Commission under the The Korean War Armistice Agreement. But I cannot find the documentation that actually establishes the JSA itself. PS - It is NOT this: https://peacemaker.un.org/koreadprk-militaryarmistice53 https://peacemaker.un.org/koreadprk-militaryarmistice53 that's just the Korean War Armistice which doesn't define the JSA.
