The official EU Resolution on its relations with Russia urges Russia to provide access to Russian archives and to solve the RW case:
26. Appeals to the Russian authorities to cooperate in opening up Russian archives, enabling access for researchers and declassifying relevant documents, including in relation to the fate of Raoul Wallenberg, who 70 years ago saved thousands of Hungarian Jews from genocide
This is a significant development, underscoring the importance EU members attach to solving the issue.
