U.S. would defend allies from N Korea - Biden at G20

STORY: Biden met with Xi for more than three hours ahead of the G20 summit in Bali, their first face-to-face meeting since Biden took power last year.

Biden said Beijing has an obligation to attempt to talk North Korea out of conducting a seventh nuclear test, although he said it was unclear whether China had the ability to do so.

He added that Russia's withdrawal from the Ukrainian city of Kherson was a "significant victory" for Ukraine, but that it was hard to tell at this point what the Kherson victory means in the wider context of the conflict, but reaffirmed that the U.S. would keep up its support for Ukraine.
