Marriage of Convenience: How European Far-Right and Far-Left Discovered China - [January 2025]

Some European far-right and far-left political parties have discovered an unlikely area of convergence: a degree of alignment with China. While not universal across the ideological spectrum, certain parties and individuals within both groups have leveraged overlapping arguments to challenge the more critical stance adopted by several EU members and the European Commission toward Beijing. This emerging alignment, though nuanced and varied in intensity, holds potential implications for EU-China relations and the broader political dynamics within Europe.

The Orange Jackass and his bootlicking ghouls did the most obvious thing? I am shocked - shocked I say!

Reform UK and AfD are also openly boosted by the US government.

Who says they're not boosting far right candidates everywhere? It's not only Russia, China etc that has social media presence for propaganda. The far right movement is organized and they visit Hungary and Victor Orban for conferences.
