Conservative billionaire Sebastian Pinera was sworn in Sunday to his second term as president of Chile, replacing socialist Michelle Bachelet in the office for the second time in eight years.
An emotional Bachelet helped Pinera put on the sash of office, gave him a kiss and then left the Congress with members of her government.
Pinera, who was president from 2010-2014, has promised to stimulate growth and create jobs.
He is assuming the presidency just as Chile's economy is showing signs of rebounding from a period of sluggish growth due to low prices for copper, the country's biggest export.
"The good times are coming," his supporters chanted after he was sworn in. He was to deliver a speech later in the day.
Bachelet was cheered by supporters as she capped a second term in office in which she saw through an ambitious package of reforms aimed at eliminating the institutional legacy of the 1973-1990 dictatorship of Augusto Pinochet.
In a Facebook message, she said she was "profoundly proud of the transformation that we pushed these years" and said she was convinced Chile today is more "just, equitable and free."
She was Latin America's last sitting chief of state who is a woman.
Implementing the changes she made will now be up to the 68-year-old Pinera, who says he wants to reform the Pinochet-era pension system and supports the free education system instituted by Bachelet.
"I feel I now have more experience, more maturity, more awareness of the importance of uniting Chileans; greater humility to listen, with eyes and ears that are more attentive," he said this week.
Pinera -- whose fortune has been estimated by Forbes at $2.7 billion -- has promised to transform Chile into a developed economy in eight years.
The economy has grown at an average pace of two percent over the past four years, but surged 3.9 percent in January. Analysts are predicting 3.5 percent growth this year.
