Soil degradation caused by physical, chemical, and biological processes weakens soil stability and contributes to soil contamination, underscoring the critical importance of sustainable soil management. This study examines the legislative intent, distinctive regulatory approaches, and implementation challenges associated with Korea’s Soil Environment Conservation Act (SECA) and China’s Law on the Prevention and Control of Soil Contamination (LPCSC). Korea and China differ in their geology, geography, and territorial scale, resulting in clear differences in soil formation, utilization, and management. Both laws embody a shared fundamental commitment to safeguard soil quality to protect public health and ecological integrity while reflecting the unique geological, geographical, territorial, and social contexts of each country. Both laws emphasize proactive prevention, the polluter-pays principle, and systematic monitoring and information sharing as essential pillars of effective soil governance. The two laws also reveal notable distinctions. The SECA, which was enacted earlier, reflects Korea’s adaptive response to industrialization; however, the LPCSC, a more recent and comprehensive statute, addresses China’s broader and more accumulated legacy of contamination. Accordingly, this study provides valuable insights into the evolution of soil environmental laws, implementation challenges, and potential pathways for developing more effective soil policies.
