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

Country [China] needs to continue opening up and keep connecting. It needs to realize that the world has become one. The old concept of isolation, the idea that you can solve your problems on your own does not work anymore - neither in cultural, economic, nor political terms.

Chinese no longer crave so much for food and accommodation, but they do crave democracy. I stand by that. I don't know which model China will follow.

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.

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.

I used to ask myself why American universities are financed through endowments. Now I know: During the early days of America, the state was poor and when citizens wanted to set something up, they needed to collect money themselves. Historically, this was different in Europe. There used to be a strong state, a monarch or a king. He provided money.

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.
