Chinese have been observing the sanctions when you look Crimea example from 2014. This give indication to west that every Chinese product has western IP or China need western markets. so for them China is not much different than Turkey or Iran.What do Iran and Turkey have in common? They've both had drones deployed in war. First they said Turkey wanted to trade with China drone tech in exchange for stealth tech. Now Iran is selling 15000 drones to China? Just like with the balloon fiasco with the US, they have to somehow make it out China is inferior to counter all the Chinese advancements its made. They're perpetuating their propaganda that China needs "them" more than the world needs China. Please, US, slap sanctions on China for helping Russia in their war in Ukraine as they lie and charge. Then China can test all its weapons on the battlefield like the West does it.
I dont think there is any official car dealer of Chinese brand in Crimea. There was no Huawei brand store in Crimea. or any Chinese contractor made infrastructure in Crimea. forget any direct Chinese tourist flights.
Russian invited Erdogan to big Mosque opening in Crimea but he not dare to cross this line.
Crimea is place that Russian spend fortune not just military or bridge. where you can find snow, trees, peaks right on ocean in February.
