Public confidence about improvement of air quality across the country remains moderate at best, according to a recent report from the Chinese Academy of Social Sciences.

Less than half, 47.4 percent, of those surveyed said they believe the country's air quality will improve in the next three years, while 14.9 percent said they believe air pollution will get worse, the report said.

More than 37 percent of people polled said they are dissatisfied with the air quality in their cities, with only 28 percent saying the quality was satisfactory.
