In terms of infrastructure, Turkey is just beginning to build a high-speed rail network. and I think the main high-speed rail link from Europe to Asia and Africa, one line from the top of the Black Sea through Russia to Central Asia. Another via Turkey, one branch goes south of the Mediterranean and the other into Iraq and Iran along the two rivers. It can be connected to the local high-speed rail network in Turkey. The Black Sea should have a high-speed rail network, the Middle East has its own high-speed rail network. how to design? It should be determined in the intercontinental main trunk road, and then expand the branch networks. Turkey's road system is relatively well developed and has a relatively high quality and strong construction team. Therefore, in the development of the Black Sea Economic Circle, the Mediterranean, the Middle East Economic Zone, Turkey's Persian Gulf Economic Zone, there should be great potential for development.
