Yes, it was in early 90s. I have never denied the amicable relations of China and Iran in 90s and early 2000s. The issues started in late 2000s.
Yes, when Saudi Arabia had severed her ties with Iran and was actively fighting Houthis of Yemen, blaming it on Iran. Also, openly threatening Iran with use of force by people like Bin Salman and their Minister of Foreign Affairs.
Good lecture. Now please lecture Persian Gulf Arabs on that too. They are the ones that constantly ask the US for "cutting the head of the snake" and are in a hidden relationship with Israel.
That wasn't the point and you know it too.
