The European Union is hopeful U.S. President Barack Obama's message to Iran can help thaw relations between Tehran and much of the world.
EU foreign policy chief Javier Solana said in Brussels Friday that the broadcast appeal could help open "a new chapter" for relations with Iran.
Solana also called Mr. Obama's attempt to reach out to Iran constructive.
Like the United States, the EU accuses Iran of trying to develop nuclear weapons and has imposed a series of sanctions on Tehran.
Last month, German Chancellor Angela Merkel threatened to impose additional sanctions on Iran if talks do not work.
