It is a very long article to say that people who live in places with polluted air have more risk of pulmonary disease (!), either as a direct result of the noxious particles in the air or a greater risk from catching lung (and other) diseases because their lung (and other) tissue is damaged and/or their general health is impaired. It impacts on the lungs, heart, blood vessels and almost every, if not all, organs and tissues of the body - it even impacts on pregnancy. I have to say that this is a very well known fact by scientists and non-scientists alike - probably just about the most well-known fact.
As for reductions in air-pollution in China, I think you confuse 'cause and effect' - air pollution dropped principally because factories closed.
Of course if we had no air pollution then fewer people would die of any illness or disease linked to air pollution.
