UN Secretary-General Ban Ki- moon on Friday arrived in Morocco, where he is expected to address an international policy conference and identify three main challenges, UN spokesman Martin Nesirky told reporters.

"The secretary-general arrived in Marrakesh, Morocco, today. On Saturday, he will address the opening session of the World Policy Conference 2010, which is organized by the French Institute of International Affairs," Nesirky said at a news briefing.

"The conference will focus this year on the theme of global governance," he said. "In his remarks, the secretary-general is expected to say that, as global interdependence deepens, some of our old systems and set-ups have not kept pace. Better ways of working together need to be found."

"The secretary-general will identify three main challenges for global governance: making sure the world economy works for all people; combating climate change; and addressing new-generation challenges such as migrations and organized crime," the spokesman added.

After his Morocco visit, Ban will travel to Strasbourg, France, where on Oct. 19, he will address the Council of Europe on the occasion of the 60th anniversary of the European Convention on Human Rights.

On that same day, Ban will also address the European Parliament in plenary session and meet with the secretary-general of the Council of Europe, and the president of the European Parliament.
