【明報專訊】THREE DAYS before Donald Trump became president of the US, President Xi Jinping had spoken at the Davos World Economic Forum and in the United Nations headquarters in Geneva. The two speeches are a response to impending changes in the world and China's answers to politico-economic questions the world is to be faced with. They are regarded as a plan China has offered the world for solving various international politico-economic problems. They are meant to be a declaration to the rest of the world and to be regarded as a set of guidelines at home. They may also be regarded as a policy blueprint of the section on international diplomacy of the report he is to deliver next autumn to the 19th National Congress of the Communist Party of China.
