In his keynote address titled "Keep Development in Focus and Create Prosper- ity for All," Li pointed out that China is still the largest developing country in the world, and that against the backdrop of a deeply integrated world economy, China and the developed countries can build a relationship focused on international production capacity collabora- tions and third-party market explorations. His assertion underscores China's new model of international eco- nomic cooperation. 展开更多
