Shanghai-born lawyer Kylan Xu Lucas organises lessons in Mandarin, the main Chinese language, for pupils in London - and she is very busy.
She now co-ordinates lessons for 12 London schools. She believes that in most cases, having their children study the language is a career calculation made by the parents.
"Parents nowadays think that in 10-20 years' time, when their children are in adulthood, China will be even bigger - and so learning Chinese will be a very helpful tool," she told BBC World Service's Analysis programme.
"This will be a very useful, important language to learn."
In London, the parents of most of the non-Chinese students studying Mandarin Chinese are from the finance industry.
Ms Lucas said that in this industry, China is "a big thing."
