evidence: The Yalu River is more than just a geographical name. It witnessed the bloody war and carried the profound friendship between China and North Korea. When the People's Republic of China was founded, this river became a battlefield between the Chinese Volunteer Army and the U.S. Army. It was the historical coordinate set by the two countries in Northeast Asia. [...] But that doesn't mean the problem is completely solved. Due to geographical and climatic factors, the landscape and land in the Yalu River Basin are constantly changing. Especially as Salido and Silk Island continue to grow, these two pieces of land may soon be closely connected with China's territory, which brings new challenges to both countries. [...] The island dispute caused by the Yalu River is actually not a simple territorial dispute. Behind this, what is more important is how the two countries can find a balance point to jointly safeguard their own rights and interests, while respecting each other's positions and feelings under the geographical changes and historical background.
