For decades the West has lectured the East on how to manage its economies. Not any more.

Now the emerging economies of Asia look like models of steady, consistent policy and sustained growth while Europe, America and Japan are mired in debt and are growing achingly slowly, if at all.

So what can the West learn from the East?

According to former Malaysian Prime Minister Mahathir Mohamad, the message is simple but devastating: Europe must face up to the new economic reality.

"Europe... has lost a lot of money and therefore you must be poor now relative to the past," he reasons in an interview with BBC World Service's Business Daily.

"And in Asia we live within our means. So when we are poor, we live as poor people. I think that is a lesson that Europe can learn from Asia."

Dr Mahathir is well qualified to pass judgement.

If any Asian leader can make claim to having laid the groundwork for his country's economic expansion, it is he.

During his two decades in power, Dr Mahathir helped transform Malaysia from a sleepy former colony into an economic tiger.


But his advice will not make happy reading in the capitals of Europe.

Dr Mahathir believes European leaders are in a state of denial.

"You refuse to acknowledge you have lost money and therefore you are poor," he says.

"And you can't remedy that by printing money. Money is not something you just print. It must be backed by something, either good economy or gold."

Dr Mahathir may be 86 years old, but he still holds very strong views.

In particular, he believes Europe and the West must begin the long slow process of restructuring their economies to reduce their dependence on the financial sector.

"I think you should go back to doing what I call real business - producing goods, providing services, trading - not just moving figures in bank books, which is what you are doing."

His big bugbear is still currency trading, which he believes did huge damage to the Malaysian economy during the financial crisis that hit Asia in the late 1990s.

"Currency is not a commodity", he says.

"You sell coffee. Coffee… can be ground and made into a cup of coffee.

"But currency, you cannot grind it and make it into anything. It is just figures in the books of the banks and you can trade with figures in the books of banks only.

"There must be something solid to trade, then you can legitimately make money."
