From Beijing Youth Daily, via the Press interpreter, translated by Joseph McMullin:
Air quality trends are not promising. The Environmental Protection Agency will increase enforcement of environmental laws.
May 20 – Yesterday, Beijing’s Environmental Protection Agency announced that so far this year there have been 88 days where the air quality met or exceeded level two standards. The number of “blue sky” days currently exceeds the five year average of “blue sky” days by 25, bringing the total percentage of clear days to about 63%.
