In this exclusive interview, CMG's Zou Yun sits down with world-renowned economist Professor Jeffrey Sachs of Columbia University. Professor Sachs, author of "The End of Poverty," praises China's eradication of extreme poverty as a "great historical accomplishment." He argues that China's transformation from a poor country in 1980 to one that eliminated absolute poverty by 2020 provides a clear "roadmap" for development, particularly for Africa.
