If you will talk to me about China's economy.
Sure! The People's Republic of China was a Soviet-style centrally planned economy from its founding in 1949 until late1978.
Sorry, I should have specified but will you tell me about its modern economy.
All of my information is about their past economy but I can tell you something more recent. China's nominal GDP, totaling 13.5 trillion US dollars, was the second-largest economy in 2018.
Okay. Yes that works. What do you know about China's infastructure.
I'm afraid I don't have that information, but I can give you another fact on the Economy. By the year 2030, the IMF forecasts that in terms of nominal GDP, China will overtake the US.

What are some popular airports?
