ED China's accountability on dust pollution

Beijing must take concrete steps to minimize regional impact from dust
A recent analysis by the National Institute of Environmental Research, conducted in collaboration with NASA, has revealed the true origins of Korea’s recurring ultrafine dust problem.
Released last month, the study found that about 55 percent of Korea’s ultrafine particles, known as PM2.5, originates from China, while only 29 percent stems from domestic sources. These figures confirm what Koreans have long suspected: The hazy skies and hazardous air quality experienced throughout the year are not solely the result of local conditions but are significantly shaped by pollution that drifts across our borders.
The Korean government has set ambitious and laudable goals: a 2 percent cut in ultrafine dust and its precursors this year, a reduction in total emissions to roughly 129,000 tons and a 5 percent reduction in national average PM2.5 levels, from 20 to 19 micrograms per cubic meter. Meeting these targets demands stringent regulation, costly industrial adjustments and sustained public cooperation. Korea is clearly taking responsibility for what it can control.
But even the most stringent domestic policies will have limited impact if more than half of the pollutants in our air originate elsewhere. Korea cannot keep tightening its own policies while simultaneously inhaling the consequences of China’s industrial emissions. Unless China acts decisively, Korea will remain trapped in a cycle of spending more, regulating more and sacrificing more, only to watch its efforts undermined by forces beyond its control.
The government has highlighted continued cooperation with China as a central strategy, sharing daily forecast data, exchanging policy measures, coordinating alerts and discussing high-pollution episodes throughout the seasonal management period. Such collaboration is necessary and welcome. However, information sharing alone is no longer enough. We have reached a point where Korea must call for more than dialogue; it must call for accountability.
China has both the responsibility and the capacity to address the problem. The world has seen Beijing mobilize its regulatory machinery to clear skies for major international events, shut down factories overnight and impose strict emissions controls when politically necessary. The fact that it can deliver cleaner air on demand makes its reluctance to address the regional spread of pollution even more glaring. If China can clean its own skies for a summit, it can certainly do more to prevent harmful particulates from traveling across national boundaries and damaging the health of its neighbors.
It is time for Korea to elevate the issue from routine intergovernmental exchanges to a matter of regional public health and environmental justice. The government should demand concrete, verifiable action plans from China, including targeted reductions in emissions from industrial zones known to affect the Korean Peninsula. Transparent, real-time emissions data from China would enable Korea to independently evaluate pollution sources and trends.
Korea should also explore compensation or burden-sharing mechanisms, not as punitive measures but as recognition of the measurable environmental, medical and economic costs China’s pollution imposes on Korean citizens. If bilateral cooperation continues to yield only incremental progress, it can pursue international environmental frameworks or even legal avenues.
Critics may argue that confronting China risks diplomatic tension. But refusing to act carries a greater cost. Every year, Koreans spend vast sums on health care, air filtration systems and protective measures. Schools cancel outdoor activities. Children, the elderly and vulnerable populations suffer disproportionately. There is a limit to how long a government can ask its citizens to shoulder these burdens while avoiding frank discussions with the primary external contributor.
The science is clear, and so is the moral imperative. When more than half of Korea’s PM2.5 originates from China, any solution that avoids addressing the source is partial at best and ineffective at worst. Korea must continue to improve its own environmental standards, but it must also make unequivocally clear that clean air is a right, not a diplomatic favor.
It is time to move beyond courtesy and toward accountability, compensation and coordinated regional action. The health of the Korean people demands nothing less.
