Secretary General Says Obanta Attendance At Rio+20 Summit 'Crucial' to Its Success

摘要

President Obama's attendance at the upcoming U.N. Conference on Sustainable Development is "crucial" to its success, U.N. Secretary-General Ban Ki-moon said April 20, adding that world leaders "count on the United States" for leadership in world environmental and poverty reduction efforts. Ban said more than 130 heads of state are planning to attend the June sustainability summit, known as Rio+20, which will mark the 20th anniversary of a Rio de Janeiro summit that launched U.N. conventions on climate change, desertification, and biodiversity.
