ROME — Italy’s new premier says he will aim to spur economic growth and achieve fairness in carrying out urgent measures to keep the country from financial disaster.

Mario Monti, an economist, says what Italy does in the next few weeks will determine the fate of the euro.

He says his one-day-old government will aim for “fairness” in implementing measures he has warned will mean sacrifice for Italians. He says his priorities include lowering Italy’s staggering ratio of debt to GDP, now at 120 percent.
