The article specifically mentions Phoslock but does not say that this "clay" is Phoslock but rather that it is like Phoslock but cheaper. As I said, the article does not say what the product is but I suspect that it is nothing to do with PHK.
By the way, there will be no translation of the Chinese article forthcoming from PHK. Not necessary apparently.
