I think it’s less about finding news without propaganda and more about knowing the biases of particular outlets and even particular authors. For instance this article come from The Guardian, which is a reputable UK news outlet that leans left of center, and has a heavy focus on environmental reporting. But this is also an editorial, so it’s going to be a little more idiosyncratic in its view than just straight Guardian reporting. With that in mind, I know that this editorial is likely going to be pretty critical of China (other than probably to praise China’s green investment to push Western countries to do the same).
Truth is every outlet has its slant, some MUCH more extreme than others, but any news should be read with a critical eye.
