Ji said 120 billion yuan (US$15.69 billion) had already been invested in environmental improvements over the past decade and at least another 25 billion yuan would be spent over the next year to clean the city’s air. "Problems still exist and there is a long way to go to meet the higher standards needed for the Olympic Games," said Ji. "We are confident we will achieve our goals."
Improving air quality is one of the biggest issues facing Beijing, which is regularly blanketed in smog.
