The issue started when actress Jun Ji Hyun and actor Kim Soo Hyun signed the contract to film a mineral water commercial in China, which marked the origin of water as Changbai Mountain instead of Baekdu Mountain. The Chinese government marks the mountain as Changbai Mountain, and the name Baekdu Mountain is officially prohibited for use. The Korean government sees Baekdu Mountain as part of its property and argues for Baekdu Mountain as the correct name.
