US President Donald Trump finished his state visit to China, Japan and the Republic of Korea (ROK) as of Friday morning. Research Fellow at China Institute of Fudan University Wang Peng says, based on Trump’s speech to South Korean National Assembly, Trump didn’t show a change of mind on the DPRK nuclear crisis. However, during his visit to China, he reached more agreements with Chinese President Xi Jinping. It is a good sign that China and the US will have more constructive and robust cooperation in the near future.
