Ian Bremmer shares his insights on global politics this week with a look at the NBA's latest rift with China, Brazil's Senate investigation, and COVID booster shots.

China wipes Boston Celtics from NBA broadcast after the "Free Tibet" speech from Enes Kanter. Is NBA boxing itself into a corner?

Nice mixed sports metaphor there. NBA has some challenges because they are of course the most progressive on political and social issues in the United States among sports leagues, but not when it comes to China, their most important international market. And you've seen that with LeBron James telling everyone about we need to learn better from the Communist Party on issues like Hong Kong and how Daryl Morey got hammered for taking his stance in favor of Hong Kong democracy. Well, Enes Kanter's doing the same thing and he's a second-string center. Didn't even play yesterday and still the Chinese said that they were not going to air any Boston Celtics games. Why? Because he criticized the Chinese government and had some "Free Tibet" sneakers. This is a real problem for a lot of corporations out there, but particularly publicly, the NBA. Watch for a bunch of American politicians to make it harder for the NBA going forward, saying how dare you kowtow to the Chinese when you're all about "Black Lives Matter" inside the United States. No fun.
