But we should no longer have to rely on China for ANYTHING.
Unfortunately it's not that simple. China supplies raw materials for electronics, shutting off that supply could disrupt markets until alternative sources can be developed. More importantly, China holds about 5% of US debt, not refinancing that could also cause short term borrowing costs to rise; impacting our economy.
Relying is a broad term, and both countries traded during the Cold War and cooperated in other areas as well.You didn't see the US relying on the Soviets for anything during the Cold War, did you?
