At the last G20 summit, Xi Jinping informed Theresa May that Britain and China must ‘shelve their differences’ over Hong Kong. Xi could not be more correct. Britain has been in a state of perpetual decline since its superpower heyday in 1914. During the 20th century, Britain ceded its empire and global status without formulating a new role on the global stage. Britain’s historically backward outlook suddenly appeared to shift in 2015 with the declaration of the creative and forward-looking ‘Golden Age’ of British-Chinese relations. Predictably, Britain has since backtracked. To prevent a directionless twenty-first century, Britain must look back to China.
