Abstract A better grasp of Trumps “new deal” could help us better understand the current situation and predict the direction of the USs future domestic and foreign affairs. The connotation of Trumps “new deal” could be analyzed in 3 dimensions: domestic affairs, foreign affairs and social trend of thought. As for domestic affairs, it mainly presents in 4 elements: taxcut, employment promotion, seeking support from the voter, and antiimmigration. The effect of the domestic “new deal” is expressed as a drive of the domestic economy, and the governance result is relatively good. In the aspect of foreign affairs, it is embodied in the principle of “America First”, which inherits and carries forward the “three magic diplomatic weapons” of the Republican presidents since the 20th century. With the social trend of thought, Trumps “new deal” has broken the socalled “political correctness” and “moral correctness” of Americas pluralism cultural, resetting the over“leftleaning” US to normality. At the same time, we should recognize and positively shape the momentum of SinoUS relations from the strategic perspective, rather than read too much into the negative impact of Trumps “new deal”.
