Don't forget the truth of the old adage: the enemy of my enemy is my friend. Differences have been put aside to promote the international terrorist jihad against the West.
The Chicoms follow a long Communist tradition of exploiting these sectarian and regional interest groups to serve as their proxies against their principal global opponents - us!
It's not even too far fetched to think of the Chicoms or North Koreans aiding and abetting Iran's nuclear quest. It's already been documented by the Israelis that some of Hezbollah's arsenal originated in China.
They where from China, But those where old rockets from Iran, The C-802 is a piece of shit, Well the original one. Iran later on added new technology in it that revigourized it.
Technically speaking The Commies really couldnt have done anything because Iran gave the weapons that where sold a decade earlier.
