President Moon Jae-in says South Korea is expanding cooperation with China on the fine dust issue, but a seasonal response system is required to clean up the nation's air.
His remarks came during a cabinet meeting Tuesday, taking place at the start of the high concentration season between December and March.
President Moon introduced various measures, including limiting the use of grade 5 emission vehicles in metropolitan areas and suspending operations of coal power plants.
He asked for support from the local governments of Seoul, Gyeonggi and Incheon, so they can be applied nationwide at a later date.
He also called on the National Assembly to pass related bills as fine dust directly affects public health.
The president will further discuss the issue over lunch with members of the National Council on Climate and Air Quality a presidential committee in charge of tackling the fine dust problem.
President Moon is expected to map out pan-national measures with its chair, former UN chief Ban Ki-moon.
