Sebastian Pinera, Conservative billionaire sworn in as Chile’s President on Sunday. Pinera returned to the job after four years of center-left rule with promises to revive investments in the world’s top copper producer. Pinera, who governed Chile in 2010-2014, accepted the presidential sash from outgoing socialist president Michelle Bachelet in a ceremony in the Pacific port city of Valparaiso. He was elected in December with a strong mandate, marking a new rightward shift in South America after conservative leaders rose to power in Peru, Brazil and Argentina. Presidents from across the region attended Sebastian Pinera’s swearing-in ceremony, including Brazil’s Michel Temer, Mexico’s Enrique Pena Nieto, Bolivia’s Evo Morales and Argentina's Mauricio Macri.
