Secretary-General Ban Ki-moon has appointed the leaders of Indonesia, Liberia and Britain to co-chair a panel that will advise the United Nations on promoting economic development after the Millennium Development Goals expire in 2015.

World leaders in 2000 agreed to a series of Millennium Development Goals to be met by 2015, including cutting extreme poverty by half, ensuring that all children have an elementary school education, halting the HIV/AIDS pandemic and reducing maternal and child mortality.

Ban told the General Assembly on Wednesday that Indonesian President Susilo Bambang Yudhoyono, Liberian President Ellen Johnson Sirleaf and British Prime Minister David Cameron will head a high-level panel "to advise on the post-2015 way forward."

He also plans to appoint a new assistant secretary-general for post-2015 development planning.
