Obama says NATO defence spending needs upward trajectory
At a news conference with Italian Prime Minister Matteo Renzi, Obama welcomed an International Monetary Fund aid package for Ukraine, calling it a major step forward that should help stabilise Ukraine's economy as it prepares for elections in May.
He urged the U.S. Congress to move quickly to approve assistance for Ukraine.
Obama took note of the fragile nature of European economies, saying those capitals with budget surpluses should help lift demand in Europe as a way to boost the European economy overall.
