In his official announcement of the nomination just now George Bush set out various reasons for his choice of World Bank president. They include that Robert Zoellick is:
“a committed internationalist.”
“He has earned the trust and support of leaders from every region of the world”.
Zoellick also spoke to journalists. He said “The World Bank has passed through a difficult time for all involved. There are frustrations, anxieties and tensions about the past that could inhibit the future. This is understandable but not without remedy. The World Bank has a vital mission to overcome poverty and despair through sustainable growth and opportunity”.
