President Vladimir Putin acknowledged Thursday that China had "questions and concerns” about Russia’s war in Ukraine, a notable, if cryptic, admission that Moscow lacks the full backing of its biggest, most powerful partner on the world stage.

Putin met China’s leader, Xi Jinping, on Thursday in their first in-person meeting since Russia invaded Ukraine, and as Xi traveled abroad for the first time since the start of the pandemic. But rather than put on a show of Eurasian unity against the West as Russia struggled to recover from last week’s humiliating military retreat in northeastern Ukraine, the two leaders struck discordant notes in their public remarks — and Xi made no mention of Ukraine at all.

"We highly appreciate the balanced position of our Chinese friends in connection with the Ukrainian crisis,” Putin said in televised remarks at the start of the meeting. "We understand your questions and concerns in this regard.”
