What are the ramifications of the US ban on Russian oil imports? Are there any surprises on Russia's released list of unfriendly countries? Also, is President Xi facing a hard wartime choice for China? Ian Bremmer shares his insights on global politics this week on World In :60.

First of all, what are the ramifications of the US ban on Russian oil imports?

A couple of things. First of all, the United States doesn't really get much oil at all from Russia. Oil product is a different story. Interesting to see where exactly that lands but it's definitely a significant message from the United States. Last week, the Americans weren't planning on that but given a lot of domestic pressure, including from Congress, the Biden administration decided to move on it. One problem I see is that this was not well coordinated with the Europeans, almost every other message so far in response to the Russian invasion of Ukraine has been incredibly strong coordination between the Americans and the NATO allies. That is not the case here. And I think that is a challenge. The Europeans are not going to be willing or able to go nearly as far as the Americans because they have a hell of a lot more to lose and that potentially makes the NATO alliance look a little bit weaker on this issue. They're going to need to communicate well on it.
