40 The Earth Observation Summit II was held on Sunday, April 25th, 2004 at Hotel Okura in Tokyo, Japan. 43 countries (including Japan) from G8, Asia, Europe, Africa, Latin America, etc and the European Commission participated in the Summit. Among the participants were the Honorable Michael O. Leavitt, Administrator of the US. Environmental Protection Agency, Dr. John M. Marburger, Science Advisor to the President and Director of the Office of Science and Technology Policy from United States and Minister Guanhua Xu from the Ministry of Science and Technology of China, Ministers from Gabon, Guatemala and Israel. To name the few of the participating 25 organizations were IBRD (The World Bank Group), U.N. Educational, Scientific and Cultural Organization (UNESCO) and World Meteorological Organization (WMO), which made the grand total of the participants to approximately 350 people.
