Melinda Liu describes the current relationship between authoritarian buddies Xi Jinping and Vladimir Putin as a "marriage of convenience."

"They've known each other a long time, so it's not entirely awkward, but it's not entirely comfortable either.

"Each of them probably know[s] that down the road, a number of years from now, the tables will be turned and one of them will be aligned with America against the other ... It's always been like that, and it always will be like that."
