China does not have one road anymore. Once Russia invaded Ukraine the entire project collapsed. It is not possible to run the rail from China to Poland (there already was a functioning hub for China-EU railway transport in central Poland before the war) without crossing Ukraine or Russia and Belarus. And all three of these countries are kinda off-limit for who-know-how long. Meanwhile the West kinda soured on the Chinese products and offshoring so once the war is over there will be no more incentive to resume large-scale operations of the belt and road.
