Antony Blinken actually said...

"If China were to help Russia to either provide military aid or some other form of assistance, financial or in terms of other assets, that the U.S. would seek to punish China for that."

"we have a strong sense of what Russia could do next, which is opinion occluded, the use of chemical weapons."

"Plots like that is what Secretary Blinken was warning about today."

"Intentionally targeting civilians is a war crime. After all, the destruction of the past three weeks, I find it difficult to conclude that the Russians are doing otherwise."
