"The demography really concerns me because that is one area that no government policy today can possibly change for the next 50 years. China's demography is now set in stone."

Beardson is well aware that looking into the crystal ball can be dangerous when it comes to China, a country that has experienced an economic transformation over the last 30 years on an unprecedented scale.

"I think trying to micro-predict China's future is a fool's errand. I wouldn't want to get into short-term projections. What I think is easier is to see the longer-term trend. If you look at the demographics, all the people who matter for this projection that we are making have already been born. It makes it easier as you can either be a little bit wrong or you can be right. You can't be a long way wrong," says Beardson.

This approach runs against many of the more cruder economic predictions for China's future, which Beardson argues are of little use without a broader context.

"There is a strong tendency in human nature to extrapolate existing trends. Goldman Sachs will announce the exact year China will overtake the American economy, but this is just an extrapolation of the trends we are seeing at the moment.

"I would argue that throughout history trends have changed as much as they have stayed the same and we should look at the things that make trends change, like demographics and education."

With this in mind, Beardson argues, China must find new ways to maintain high economic growth as the population peaks and wages rise.

"If you are going to grow the Chinese economy by a good clip over the next few decades you need to make further reforms. You need to encourage the service sector to take over from manufacturing. It means encouraging an innovation economy, because we can no longer be a low cost manufacturer when the demographics go against that. It means tackling the education system and the universities, too."

Beardson is personally involved in education as the chairman of the China Oxford Scholarship Fund, which assists low-income Chinese students to take postgraduate studies at Oxford University.

It will be some of these ambitious young students who are tasked with tackling the problems China faces over the coming decades.

"The Party has been extraordinary successful at adapting itself since the time of Mao Zedong. I just feel there is a case for saying that over the last decade that adaptability has been less evident.

"I'm really calling for the Party and the government to improve the governance with which they implement the policies. The policies are not necessarily bad, they are often quite good.

"But they are often not implemented. I'm not discussing government. The government has delivered fantastically for 30 years. I think the last 10 years are an example of China being a bit lost. I would just like to see re-engagement and a commitment to real reforms."

While Beardson is critical of certain choices China has made, particularly over the past decade, he hopes his book will be welcomed within the country. He dedicates Stumbling Giant to China, wishing the country a prosperous, successful and happy 21st century.

"I will have to take the risk that my book is misinterpreted by some, but I think there are lots of people who are aware I am a friend of China."
