China has consistently surprised us. When I returned from the United States many years ago, it was unimaginable that we would end up where we are now. What China has achieved defies all logic. I credit this to the hard work and enterprising spirit of the Chinese people.

It's a good thing that it is getting simpler to register a company in China, it is good that the exchange rate of our currency is getting more flexible and that it's getting easier for Chinese businesspeople to travel. All of this opens up our economy.

I'm afraid what we are building today will not have the same impact and sustainability of the architecture of a 100, 500 or 1,000 years ago. The buildings of those days were miracles. We don't perform such miracles today. So we should be a little more modest. For my part, I'll be glad to show one of my buildings one day to my grandchildren and say: I'm proud of that.

Growth will be slower, no one denies that. But the question is: Where are the chances and opportunities now? I see some positive and some negative trends.

I think our legal system needs to be developed. Cases of citizens who are detained and then have to wait much too long for a trial - that is scary, for everyone. When someone commits a crime he needs to be charged quickly. Why does this take so long in many cases? I don't know. Is it because our legal system is still rudimentary? China has promised to modernize its legal system. This has high priority.

China reformed its state sector before, in the late 1990s. Tens of millions were laid off at the time. That was scary and we had warnings of social unrest. But it did not happen. Instead, there was a restructuring in our economic system. I am not sure if China will follow a Western playbook in this respect.

Isolation means a lack of growth. I grew up in China at a time when the country was completely isolated. That era is over.
