The signing ceremony for the Agreement on Academic Exchange and the Memorandum on Student Exchange between the Graduate School of Public Policy (GraSPP), the University of Tokyo, and the School of International and Public Affairs (SIPA), Columbia University, was held on March 13, 2006, at a reception celebrating the 60th anniversary of SIPA at Roppongi Hills, Tokyo. This is the first international agreement that GraSPP has ever entered into with any other school, and has enabled GraSPP to do various things, i.e., exchange of faculty members and researchers, exchange of students, exchange of academic information and materials, conducting collaborative research projects, conducting lectures and organizing symposia and so on. The first exchange of students is likely to take place in this autumn.
