Iranian arms built with Chinese parts that use sanctioned US parts...
That would make it interesting!
I get the impression Iran is not happy with China’s level of support.
“Iranian arms built with Chinese parts”
China provides Iran with a lot of its missile capability, like the old Silkworm cruise missiles they have threatened shipping lanes with for so long.
The North Koreans and Iranians attend each others’ nuclear and missile tests, and collaborate with each other on their programs. China is behind both.
