No.
Firstly, the Chinese Navy does not have the capability to confront the US Navy in the Persian Gulf.
Secondly, China's oil security policy is excellent, and simply interrupting oil in the Persian Gulf is unlikely to affect China's economy.
China is likely to assist Iran through military aid.
Trump has threatened China that if China provides military aid to Iran, he will increase tariffs by 50% on China.
Today, the Chinese Ministry of Foreign Affairs responded that restarting the tariff war is not a good choice for the United States.
In the context of Chinese language, this answer is equivalent to acknowledging that Iran will receive military assistance and accepting the resumption of the tariff war.
