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.

But it is a worry that there have been so many delays in the reform of China's state-owned enterprises. We all know that private companies are run more efficiently than state ones. These reforms are very much anticipated for the potential dynamism they could create.

No economy, no company, in fact no individual can develop its full potential today without embracing two fundamental trends - globalization and digitalization. They will dominate for quite some time to come.

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.

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.

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.

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.
