European countries should seriously discuss Putin's agression with their most important trading partner, China. Xi may think that it has a free ride on the Russia vs EU conflict, by having cheap Russian energy with which it produces price-competitive electric cars China exports to the EU. But that may soon come to an end when the EU makes it clear that it can no longer do "business as usual" with a country that holds joint naval exercises with Iran and Russia, and will raise trade tariffs. China (btw Russia’s largest drone supplier in the Ukraine war) is the only country Putin will seriously listen to.
