WASHINGTON (AP) — The United States and its European allies are finalizing a package of sanctions on Russia’s key economic sectors that could be levied as early as this week, though the penalties might be delayed because of positive signals from Russian President Vladimir Putin, administration officials and others close to the decision-making said Tuesday.

Penalizing large swaths of the Russian economy, including its lucrative energy industry, would ratchet up the West’s punishments against Moscow over its threatening moves in Ukraine. The U.S. and Europe have already sanctioned Russian individuals and entities, including some with close ties to Putin, but have so far stayed away from the broader penalties, in part because of concern from European countries that have close economic ties with Russia.
