Russia Rejects New EU Sanctions as Illegal, Vows Response

The significance here is less the sanctions themselves than Moscow's explicit refusal to treat EU measures as legitimate, framing them as a UN Charter violation rather than a policy dispute. That argument is aimed well beyond Brussels, at states weighing whether to align with EU restrictions. The open question is what form the promised response takes, and whether it targets European assets or diplomatic channels — that, rather than the rhetoric, is what markets and counterparties will watch.
