Angel Gurria, the former Mexican foreign affairs and finance minister and now secretary-general of the Paris-based OECD, emphasized "innovative" as well as "dynamic" and "flexible".

"One of the most visible changes in China is the abundance of internet-based services, including mobile payments and shared economy services," he responded.

"These innovations have changed Chinese people's lives, well ahead of many other more economically advanced countries."

"Innovative" also featured in the choices of Alain Crozier, chief executive officer of Microsoft China, alongside "dynamic" and "transforming".

"China has really turned the corner from being a manufacturer and consumer of technology products and services invented by others to one that is developing real breakthroughs and real value that is relevant to the rest of the world."

Colin Mackerras, a Sinologist and emeritus professor at Griffith University in Australia, selected "prosperous", "confident" and "stronger", since all three, he says, are reflected in Xi's style of leadership.

"He stands out among contemporary world leaders for his rationality and common sense. He is very impressive."
