The evidence from all provided sources overwhelmingly supports the truthfulness of the statement. Multiple high-authority sources, including a global think tank (IISS), and major news organizations (The Guardian, Associated Press), explicitly discuss a specific "plan," "proposal," or ongoing "negotiations" within the EU. The Associated Press report is particularly direct, detailing diplomatic efforts by envoys to finalize a plan to use the assets as collateral for a loan. This indicates the matter is well beyond preliminary consideration and is in an active, advanced stage of policy discussion. Further corroboration comes from a primary source, the Ukrainian government, whose Prime Minister is quoted discussing frozen Russian assets as a component of international support. An academic analysis from The Conversation also breaks down the mechanics and risks of "the EU's plan," treating its existence as a given. Even the source reporting on opposition to the proposal (Hungarian Conservative) confirms the statement's core truth; the existence of a coalition to oppose the plan necessitates that there is a concrete plan to oppose. There are no contradictions among the sources regarding the existence of these considerations; they are all consistent in reporting that the EU is actively grappling with this policy option.
