China did not have to respond to the USA when building its high-speed railway system. Sanctioned from approaching the International Space Station, China did not have to respond to the USA when building its Tiangong Space Station. China did not have to respond to the USA before going into EV manufacturing. It did not have to respond to the USA trying to demonize its domination in shipbuilding, wind turbines and solar panels.
China is not India, being told to ask the USA for permission to buy Russian oil or else. China can do what it deems essential for its National Security matters. More than that, China does not need to succumb to threats regarding its purchase of Russia oil and gas. China is now saying, USA sanctions should be ignored as far as China is concern. That message is now officially sent to oil refiners, and others sooner or later. That shows the confidence that China now has, knowing that de-coupling from the USA is on course and progressing well. China does not have to depend largely on the USA market for its products. The trade surplus that China accumulated year after year, despite exporting less to the USA, is the proof that China can move away from selling to the USA. That card can no longer be played by the USA against China and Trump can impose tariffs of 1,000% if he likes.
