Does China keep opening its doors further, or closing them? What does the resolution adopted at the 3rd plenum of the 20th CPC Central Committee say about it? Host Liu Xin sits down with Jeffrey Sachs, director of the Center for Sustainable Development at Columbia University and president of the UN Sustainable Development Solutions Network. And, a U.S. business delegation visits China right after the same meeting. We have an exclusive interview with Roberta Lipson, founder and vice chair of United Family Healthcare and a member of the delegation.
