The relationship between Vladimir Putin and Xi Jinping is a "marriage of convenience," Newsweek's Beijing bureau chief Melinda Liu tells Ian Bremmer in a GZERO World interview. "They've known each other a long time, so it's not entirely awkward, but it's not entirely comfortable either. There's ... not a lot of trust."

But according to Liu, Xi's biggest problem right now is not Putin, but China’s zero-COVID policy - which now has 26 million people under lockdown in Shanghai. China is facing a challenge they never saw coming — and that "hits right to the soul."
