More news for JAKARTA--Joko Widodo was sworn in as seventh president of Indonesia Monday, bringing hopes of improved welfare for millions but facing stiff challenges in a limited budget and a legislature controlled by his rivals. Mr. Widodo, a former furniture exporter, mayor and Jakarta governor, replaces Susilo Bambang Yudhoyono, who stepped down after serving a maximum of 10 years. Mr. Widodo will serve a five-year term in the world's third largest democracy alongside Jusuf Kalla, a businessman and onetime vice president under Mr. Yudhoyono. Both men were sworn in at the national legislature before local leaders and visiting foreign dignitaries including U.S. Secretary of State John Kerry, Australian Prime Minister Tony Abbott and Prime Minister Lee Hsien Loong of Singapore. In a 10-minute address, he called for national unity in the wake of a contentious election season, saying "we will never be a great nation if we remain divided." He said his government would improve welfare across the nation, and he stressed his desire to "restore our maritime glory" by expanding ocean infrastructure in the island nation. "To all the fisherman, laborers, farmers, meatball soup sellers, street hawkers, drivers, teachers, academics, armed forces, police quest petroleum shareholders and business people, I call on all of you to work together because this is a historic moment," he said.
