The Chinese people, in truth, oppose the current actions of the United States from the bottom of their hearts—not merely out of national interest or anti-American sentiment. As a result, they are doing their utmost to avoid becoming the next United States. This is a matter of worldview. In fact, I see it as a positive sign: it suggests that a country with imperial capabilities still harbors an aversion to becoming the next imperialist power.
However, I believe the Chinese are beginning to recognize the harsh realities of the world. From the India–Pakistan conflict, we can see increasingly direct and assertive voices emerging from both the Chinese government and the public. The unexpected decision to sell the J-35A (which surprised many Chinese) also reflects a shift—suggesting that China’s future diplomatic strategy is poised to become more proactive.
As for Iran, given that China's power cannot extend there in the short term—and considering Iran's many internal and external complexities—I believe Iran will still need to stand on its own for some time. Only after China gradually gains a clearer understanding of the situation might it intervene, whether openly or behind the scenes. As a Chinese saying goes: "God helps those who help themselves." If a people demonstrate a firm will to resist, help will naturally come.
