We have become so quick and effective in building things today. It would be easy to build another Pyramid of Giza or another Great Wall. But these buildings haven't withstood the test of time because of their building quality. They stand tall because they have a symbolic value, they represent a culture.

I firmly believe that digitalization has only just begun in China. In addition to the taxi, transport, shopping and hotel businesses, many other industries will follow: education, health care, administration, even the legal branch - everything, really. There is still a lot of opportunity in China for the inventive and ambitious ones.

Investors don't like uncertainty. The market is telling us that they need certainty, they need to see where the economy is heading. If the government is committed to continue the Open Door policy, they will need to come up with concrete policies and execution steps to increase confidence.

Many years ago, we were only able to build boxes. Today, architects from all over the world are working with us - Zaha Hadid from London, Gerkan, Marg and Partner from Hamburg, Kengo Kuma from Japan. We brought design and digitalization from abroad to China.

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.

We are not very good at this. Our success rests on our international experience and on our ability to read the market. And I contest the notion that you can only succeed in China when you are well-connected. Neither my husband nor I are "princelings" - children of influential people, that is. And yet China has enabled us to succeed.

Our tenants now are companies like Uber, the taxi service, Meituan.com, China's version of Groupon - and a large number of startups. These companies operate in a modern way, just like their customers: They go on the Internet, look for an offer and take it.
