Our company has only been active in Beijing and Shanghai, two very market-dominated cities. This was an advantage. Land is purchased here in public auctions, in a transparent way. When you do real estate development outside Beijing and Shanghai it is good to have "guanxi" - good relations within the local government.

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.

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.

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.

On the one hand the world is getting more integrated and we should not dismiss social values as "Western" when they are actually modern values. On the other hand, individual countries have their own history and their own evolution. Trade unions, for example, don't play the same role in China as they do in Europe or the US.

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.

I am a runner. Last October, there was a marathon here in Beijing. I didn't participate this time, but friends told me that the run wasn't prepared too well. The organizers had only arranged about three hours' worth of food and water supplies. Most people don't finish within three hours, however. Too bad for them - or so it seemed. In fact, however, even those finishing last were perfectly taken care of, particularly during the fourth and fifth hour when demand is highest.
