China is drawing up a plan to continue the fight against its chronic air pollution problem after its previous five-year plan saw PM2.5 levels in the Beijing-Tianjin-Hebei region plummet by over 25 per cent.
The ultra-fine particles, a fraction the size of a human hair, penetrate deep into the lungs and enter the bloodstream, causing respiratory health problems.
The new plan is meant to ensure the benefits of the previous action plan, covering the period 2013 to 2017, does not backslide.
Under that plan, China managed to reach all its 2013-2017 air quality targets by the end of 2017, despite soaring PM2.5 levels levels at the beginning of the year.
