The main reason it was made a big deal was because China was denying there was a problem.
One of the main reasons China cleaned up their air pollution is because the US Embassy installed an air pollution update page that proved that the Chinese media calling the brown haze “fog” for decades was a complete farce. The pollution page got so many hits and was referenced so much that the Chinese government finally admitted the fog was pollution.
So just how sad were things in terms of the Chinese government trying to cover it up..try this 2012 article

China Asks Other Nations Not to Release Its Air Data
After years of choking smog that stings the eyes and burns the lungs, regularly documented by an air sensor at the American Embassy in Beijing that
posts the results hourly on Twitter, the Chinese government took a strong position on the issue on Tuesday.
Wu Xiaoqing, the vice minister for environmental protection, demanded that foreign governments stop releasing data on
China’s air.
...
In case anyone missed the point, a Foreign Ministry spokesman, Liu Weimin, said at a briefing later in the day, “Of course, if the foreign embassies want to collect air-quality information for their own staff or diplomats, I think that is their own matter, but we believe that this type of information should not be released to the public.”
So now the Chinese PDF members instead of being thankful are being spiteful...unreal.
How truly sad can things be if millions of Chinese people are turning to the US Embassy to supply them with real air quality data.
BTW they eventually banned Twitter...because it made news they couldn’t hide through censorship available to the masses. How admirable!
