China’s air pollution has improved in recent years, but it comes from very high pollution levels, and the country still ranks among the highest-polluted in the world.

According to IQAir, a non-profit organization, Chinese cities rank among the most polluted in the world as no Chinese city ranks among those with an air quality considered to be ‘good’.

This article is based on a Chinese study using data gained from machine learning, not real data. Conducting independent air quality studies comprising Chinese air quality data is difficult, as one study suggests (opens pdf),

The technical solutions China uses for its data-sharing platform also have limitations that can prevent outside access.

This is just another propaganda article based on purely Chinese sources posted by an apparent sock puppet that is permanently cross-posting from ml communities. That’s an inappropriate comment, please see my correction below.
