Let's be realistic here. Iran will never have a successful car industry. So it really doesn't matter that they want this. They have no realistic means of achieving it and no real markets to sell to.
Well, right now they have their own internal market. If they open their market to China they won't even have that.
So they're as ambitious as the Turks but unlike the Turks, have played their hands poorly. They don't need to make an enemy out of China but Chinese help is there for the taking and in fact, they are committed, as the 25 year $400bln Sino-Iran Agreement attests. That's $400bln that's not going into US Treasuries mind you and if any Iranian leader decides they'd rather live as slaves, then they need look no further than Argentina whose anarchy capitalist Mile was forced to kowtow to Beijing.
Everyone are ambitious, it is what it is. But yeah reformists are delusional about the west, no matter how many times they got burnt they still haven't learnt their lessons. The thing is Iran geopolitical position is pretty much set in stone, no matter how much some Iranians love America it won't change the ground reality
