Again, f*ck off.
I already explained to you why you assholes were put aside after being thoroughly tested. It's not like one day we woke up and decided that China is bad. You stabbed us in the back for years, times and times again. There's no guarantee that China would ever deliver jet fighters to us.
When you guys were a bunch of wage slaves that sold your ass for 2 cents per day, we signed the largest economic deals with you in late 90s. We established excellent economic trade with you to replace the West. You proved you didn't deserve any of it.
You're getting back to that period again soon. Trump knows that China is a threat and he's going to take care of you. And it is in fact a bipartisan policy, just like the US-Iran situation that is bi-partisan. They're onto you and it's only a matter of time.
Soon you will be back to the wage slaves you were, working in sweat camps assembling American/European products like slaves. Other than the products you assemble, almost everything else you produce is cheap and crap. So, enjoy while you can because you're next on the list.
Now review this list again to realize what sort of two-faced bitches you Chinese are:
1. You betrayed Iran 4 times at the UN Security Council which brought our economy on the verge of collapse and forced us to accept the JCPOA.
2. You abandoned Tehran-Shomal highway due to US sanctions.
3. You abandoned the Chabahar Port due to US sanctions. Chabahar was offered to you first, not the Indians.
4. You abandoned IR-40 nuclear reactor after Trump pulled out of the JCPOA.
5. You abandoned South Pars gas field in fear of US sanctions.
6. You closed the bank accounts of Iranian students studying in China after the US imposed unilateral sanctions.
7. You abandoned Tehran Metro, again due to US sanctions
8. You did nothing to restore our trade after the US kicked our banks out of the SWIFT.
