On the eve of Trump's visit to China, the Iranian Foreign Minister suddenly announced his invitation to visit China today. I see many people interpreting it as bearish, but I don't think so. Currently, the negotiations between the US and Iran are not going smoothly, and there are constant frictions between China and the US. If China can play a mediating role and communicate with Iran in advance to obtain the negotiating card, as a "goodwill chip" released to Trump's visit to China, it will become an important achievement of Trump's visit to China. Moreover, this achievement is a win-win situation for both China and the US, and Trump is likely to hope that China will use its influence on Iran to push for concessions as a condition for the US to exchange tariffs and export bans. So this is a good thing, a great thing!
