Just to point out that's a bit all over encompassing, you imply countries like japan or south korea are either not considered part of the "east", or do not have credible media. Those countries are definitely not the "west" as per the standard convention when using such a term. A second point to point to out, certain western media used to be considered credible but have since become heavily politicized and/or perceived to have a political agenda to prioritize news casting that illustrates and drives a certain narrative, examples being fox news and its morning show fox and friends being considered pro republican (or pro trump at least), and cnn being considered as pro democrats. The bbc is probably only news agency that is somewhat still credible in having objective news coverage.
