Is it possible to achieve the Hungary-Serbia-Macedonia-Greece high-speed railway? If achieved, Hungary, Serbia, and Macedonia can connect to the ocean with fast train.

1. China has good relations with Hungary, Serbia, and Greece, but Macedonia is a member of NATO. Will it support this railway, which obviously also has great interests for it?
2. This railway seems to need to pass through Kosovo, or pass next to Kosovo. Will Kosovo become a problem?

Anyway, I am glad that China can propose such an ambitious project. There is a will, there is a way.
