Research fellow at China Institute at Fudan University Wang Peng has been reflecting on the visit to Asia by US President Donald Trump. Wang says that based on Trump’s speech to the South Korean National Assembly, he hadn't changed his mind on the DPRK nuclear crisis. However, during his China visit, he reached more agreements with Chinese President Xi Jinping – a good sign, Wang says, that China and the US will have more valid and constructive cooperation in the near future.
