Dr Chris Ogden sets out some of the political and strategic challenges facing US-China relations ahead of the coming Trump Presidency. According to Dr Ogden both during and after the 2016 US presidential elections, China featured significantly in the campaign of eventual victor Donald Trump. In the President-elect’s eyes Beijing is Washington’s most dangerous strategic competitor that threatens the US’s ability to control and lead the world. Following on from his victory, Trump has continued to directly condemn China, and has in many ways accelerated his attacks on Beijing. In doing so, the new American leader appears to be at best questioning, and at worst shattering, several of the key understandings that were thought to have underpinned US-China relations, which serves to suggest that the world’s two largest economies are entering a stormy period.
