Who poisoned Russian oligarch Roman Abramovich? Does Russia's invasion of Ukraine mark the end of globalization? Will Shanghai's lockdown begin to shift China away from its zero-COVID policy? Ian Bremmer shares his insights on global politics this week on World In :60.

First, who poisoned Russian oligarch Roman Abramovich?

Yeah, it's quite a story involved in the Russia-Ukrainian negotiations, and apparently claimed that he was poisoned. And it's interesting, he is, of course, a very well-known Russian oligarch. He's made his billions of dollars, purely because of the support and alignment with President Putin. And he has been fairly public in his concern with opposition to the war. Indeed, one of the reasons why some of the sanctions have been more limited against him than they would've been is because Zelensky, the Ukrainian President, reached out to the Biden administration and said, "This guy's actually being useful to us, and so it would be, you don't want to hit him too hard." And clearly, the Kremlin is angry about that. And so, I have no intelligence at all about who would've been responsible for his poisoning, but if it happened, the list from the Kremlin would be as long as my arm.
