China, South Korea and Japan are to form two new working groups to tackle air pollution in northeast Asia.
The groups will encourage regional cooperation on technology, air quality monitoring and research.
The three countries will meet and draft a detailed action plan for the first working group, focusing on scientific research on prevention and control of air pollution this year.
This is according to a joint statement issued by the 17th Tripartite Environment Ministers Meeting in Shanghai on Thursday.
The second working group will gather scientific researchers and others to promote technology and policy on air quality monitoring and forecasting.
At the meeting, ministers from the three countries stressed the urgent need to tackle air pollution caused by PM2.5－airborne particles smaller than 2.5 microns in diameter.
They announced a joint action plan for environmental cooperation from 2015 to 2019. The plan's nine priority areas include air quality improvement, water and marine environment conservation and progress on a green economy.
China will also share more information on dust and sandstorms with South Korea through special channels, with South Korea releasing more accurate forecasts on sandstorms, Yoon Seong-kyu, the South Korean environment minister said on Thursday.
Chen Jining, China's minister of environmental protection, said in a media release that the country has taken tough measures to improve its air quality.
As a developing nation, it has faced challenges from a heavy industrial structure, huge consumption of coal and the economic gap between its eastern and western regions, making air pollution control a long-term mission, Chen said.
"But we are confident of solving this to make a contribution to the region as well as to the world."
Last year, the average concentration of PM2.5 in 74 major Chinese cities was reduced by 11.1 percent and it continued to fall－by 16.3 percent－in the first quarter of this year, the minister said.
Energy consumption
Coal consumption last year fell by 2.9 percent, the first reduction in 15 years, Chen said, adding that total energy consumption last year was 4.26 billion standard tons of coal.
China will promote the continuing cooperation with South Korea and Japan, Chen said, adding that this cooperation has grown to become a major regional environmental platform.
Chai Fahe, deputy director of the Chinese Research Academy of Environmental Sciences, said, "This regional cooperation has been an important channel for China to ease air pollution, especially in technology exchanges."
He added that cooperation in the environmental sector is a necessary and efficient way to curb regional pollution, which will benefit China and the region.
Chai conducted joint research with experts from Australia last year.
