The U.S. blocked Chinese astronauts accessIng the International Space Station, China built its own.

The U.S. banned high end chips export to China, Huawei managed to build its own 5G phones with tech  breakthrough within 4 years

What else can the US impose sanctions on China? In the end the U.S. loses the huge Chinese market as Chinese start using own brands and products instead of imported products from the U.S., so the U.S. sanction is backfired.
