US President Donald Trump’s fondness for Diet Coke – summoned via a dedicated red button on his Oval Office desk – is legendary.
The sight was unexpected in a formal state setting, yet deeply familiar to those with experience of Chinese culture.
In China, many people carry vacuum flasks filled with hot beverages once they pass a certain age, as warm liquids are thought to be better for digestion according to traditional Chinese medicine principles. Often, these flasks also contain herbs or berries believed to have medicinal value, such as goji berries. While it is unclear what Xi and Peng’s flasks contained, this is the most likely answer.
