Washington is stuck in the unipolar mindset of preserving technological monopoly through sanctions rather than fair competition
Washington has apparently been under the impression that by depriving its adversaries of access to high-end microchips, be it China or Russia, it can enforce an all-inclusive package of containment that cripples their military, technological and therefore economic development. Using its monopoly over fundamental chipmaking patents and equipment, the US has unilaterally blacklisted Chinese companies, as well as Russia in its entirety, and forced third-party countries to do the same.

This has become a core component of US President Joe Biden’s doctrine, which envisions perpetuating American hegemony through sustaining its technological monopoly. This has become the onus of the new Cold War, which is more about chips and less about nuclear weapons, as the US seeks to control the technologies of the future. However, as time goes by, no matter how many restrictions Washington imposes on adversarial countries, it is becoming more and more clear that the policy isn’t working. As an article in The Hill narrates:

“China is openly seeking to evade US export rules on semiconductors by investing in RISC-V [an open-source chip design architecture] to develop homegrown chips, undercutting years of bipartisan and international work in this space.”........
