You're spreading misinformation. This is from 2024. Obviously Iranian society was torn between turning east or west. And China and Russia have been very big on verbal support but don't really want to support Iran against the west. Chinese investment disappeared after trump's maximum pressure campaign. So what's the point of having a strong relationship with China or Russia if they are always going to choose the US market over the Iranian market? The only way to receive Chinese investment is to be a us ally! Meanwhile getting on better terms with the west in 2015 caused an economic boom. Given that background, I'm surprised you don't get more people who want to abandon the whole struggle and just join the west
But everything changed with the war in 2025. The aim of the attack was to install the old regime and the people rejected foreign intervention. The voices calling for engagement with the west have been silenced. Iran is now much more leaning east than west as a result of the war. It helps that both Russia and China are now in a conflict with the west that they weren't when the jcpoa broke down. If both sides work together, they can achieve a very good relationship.
But I'm still not sure if China actually wants a strong relationship with Iran or if China only cares about selling goods to bigger markets. And if China isn't signalling interest in a strong relationship with Iran, why would Iranian people replying to a survey say that it would be good for them to have a strong relationship with China? Because it looks like the way to get a strong relationship with China is to first get US troops on your soil
Every time there's a minor strike or protest in Iran it's blown out of proportion as if it's another revolution. There were significant cost of living protests in the UK but western media don't talk about it. Don't be a victim of radical Israeli propaganda
