Rwanda plans to sell its second international bond of as much as $1 billion next year to fund the construction of an airport and power plants, seeking to tap burgeoning investor demand, President Paul Kagame said. The East African nation wants to build on the success of the $400 million bond issued in April 2013 that was more than eight times oversubscribed, Kagame said in an interview at the U.S.-Africa Leaders Summit in Washington yesterday. At that foreign-debt sale, the government declined investors’ suggestions to increase the size of the offer, he said. “We might go for double that or more, up to $1 billion,” Kagame said. Rwanda is one of Africa’s fastest-growing economies, averaging 7 percent over the past five years. The economy is forecast to expand 7.5 percent this year and next, according to estimates from the International Monetary Fund. Kagame, who has been in power since 2000, has implemented policies that have helped rebuild the economy after a genocide in 1994 that left at least 800,000 people dead. “People who want to see Africa develop come to Rwanda particularly because we have set up a very good environment that makes things work for us and for our partners who come invest with us,” Kagame said.
