The B&R route designed by China has only three routes from East Asia to Europe. One goes to Germany through Russia and Poland, one goes to Europe through Central Asia, Iran and Turkey, and the other goes to Italy through Suez Canal and Greece.Project is dead from start.
1. Russia is a dead end, Europe cut all ties. Russia itself has very small economy. Its all about trade between East asia and Europe and that trade wont go through Russia.
2. Iran is not a trustworthy trade route. No european company will send workers to a country that is known to take hostages.
Now the first route has been interrupted by the Ukrainian war. So it is impossible for China to abandon either the Iran Turkey route or the Greece Italy route. China is not stupid enough to put eggs in one basket.
