There is a verisimilitude between those hog buildings there and the U.S. Congress. VERY BIG pork projects come out of each. Yeh, I could see a couple of those pork buildings being constructed down on K Street in DC. They would fit right in. - no problemo. That's their job down on K Street where the lobbyists' job is to bring home the bacon.
I don't get twiiter comments. If the Chinese have excess buildings that can be repurposed to do vertical farmings, provided the smell issue is not an complaint, I don't see any problem. Vertical farming is a hot space to get into, a friend of mine is converting/fixing old warehouses in PA to do just that. CBRE has a practice group to sell that.
