The European Union intends to push for sanctions against China over its support for Russia in the war against Ukraine. Source: Unnamed EU diplomat in comments to a Politico journalist, as reported by European Pravda Details: The EU made this move following a July report by Reuters, which revealed that Russia had secretly obtained Chinese engines for drones.
I don’t think this is the correct interpretation. This sentence is not an assertion that the EU didn’t know its only establishing a sequence of events. Very often politicians will react to news reports, you know, to save face etc… They just don’t want to appear to let this slide now that the public knows.
