A Pentagon spokeswoman has warned that China would face "consequences" if Beijing continues to deepen its relationship with Russia .

Over the last week, U.S. officials have revealed that Beijing is considering providing "lethal aid" to Russia for its war in Ukraine , though they have all maintained that the United States doesn't have the intelligence to prove that China has already crossed this line. However, they've raised alarm bells about the growing relationship between Beijing and Moscow.

“There will certainly be consequences for China should they deepen their relationship with Russia. We haven’t seen them give lethal aid to Russia at this time for the war, but they also haven’t taken that off the table," Pentagon deputy spokeswoman Sabrina Singh told reporters Wednesday.

She declined to specify what the consequences could look like if they do cross this line.

Days ago, Secretary of State Antony Blinken said China appeared to be "considering" taking a more active role in supporting Russia. During much of the first year of the war, China's position was calling for peace while also quietly supporting the Kremlin.

"China’s having — trying to have it both ways," he said in an interview last weekend on Meet The Press. "Publicly they present themselves as a country striving for peace in Ukraine, but privately, as I said, we’ve seen already over these past months the provision of non-lethal assistance that does go directly to aiding and abetting Russia’s war effort. And some further information that we are sharing today and that I think will be out there soon that indicates that they are strongly considering providing lethal assistance to Russia."

Earlier this week, Russian President Vladimir Putin welcomed China's top diplomat, Wang Yi, to the Kremlin and teased a future meeting with Chinese leader Xi Jinping .

Blinken and Wang met last week on the sidelines of the Munich Security Conference, where Blinken "warned about the implications and consequences if China provides material support to Russia or assistance with systemic sanctions evasion," according to State Department spokesman Ned Price said in a readout of the meeting.

Deputy Secretary of State Wendy Sherman said last week that the relationship between the Kremlin and the Chinese Communist Party has "no-limits."

The U.S. and China's relationship has continued to fray over recent months. U.S. officials have accused China's military of becoming more aggressive toward Taiwan in addition to its supposed consideration of additional help for Russia and the Chinese spy balloon that traversed the U.S. weeks ago before America's military shot it down. It has been recovered and is now being investigated.
