On diplomatic occasions, Xi used tea as a metaphor to introduce traditional Chinese culture and illustrate Chinese philosophy.

In a speech he made at the College of Europe in Bruges, Belgium, in 2014, he said: "China represents the Eastern civilization in an important way, while Europe is the birthplace of Western civilization. Chinese people are fond of tea, and Belgians love beer. To me, the moderate tea drinker and passionate beer lover represent two ways of understanding life and knowing the world, and I find them equally rewarding."
