Did the Trump organization break the law in Azerbaijan?

In Baku, the capital of Azerbaijan, there's a 33-story building shaped like a sail. Advertised as a hotel and residence, it's oddly located away from the city's business center and it's hard to reach between near-by on-ramps, off-ramps and overpasses. It has never opened. When Adam Davidson visited in December, "five enormous white letters glowed at the top of the tower," he reports. "T-R-U-M-P." Davidson wrote about "Donald Trump's Worst Deal" in the latest New Yorker magazine.
