China needs to learn that man does not live by bread and bridges alone. Westerners understand this very well.
This is a big victory for the US and Israel and a big defeat for Russia and Iran who lose important positions in the Middle East and weaken further in the diplomacy and military sphere.
Not being able to make strong allies or not being able to influence and strengthen allies is also a failure, and yes, a worrying responsibility for the future.
Everything has a price and this omission of China in the world's conflicts means that the BRICS are seen more as a losers' club than a real alternative to Western hegemony and bullying policies.
After guaranteeing control of the Middle East without difficulties, the US will now try to contain Russia. Trump will probably try to reach an agreement with Putin, which, if it doesn't work, will try to further strangle Russia's economy and military arm to its limits. Iran is just an irrelevant satellite.
Afterwards, it will be a free path to isolate China if it does not give in to blackmail. I could be wrong, of course, but I don't see this passive Chinese approach as sustainable for long. The West will not tolerate competition.
