> You can look for a long time, but you'll never find an example of a superpower/empire, or a close ally of one, submitting to any kind of international judgment against it, criminal or in a trade dispute. At most, they may accept a negative ruling to a case they brought against someone else.
Since 2020, China's Huawei has been subject to semiconductor supply chain restrictions which have been enforced by multiple countries. This has materially impacted Huawei consumer smartphone revenues.
They are enforced by other countries - it wasn't the Chinese themselves who decided to stop doing something because an international court said so - that is my point. This would be equivalent to a court imposing a fine on you, and your neighbors taking your things in the amount of the fine (instead of the state taking it, or you going to pay).
Self vs. other enforcement is less important than consequences, which are the same in both situations. If a country has the opportunity to negotiate the terms of trade, that is clearly preferable to terms being imposed unilaterally by others.
Yes, countries can break agreements, but good agreements provide benefits to all parties, such that breaking an agreement results in reciprocal loss of benefits. There are always edge cases, but by definition, not everything is an edge case and there are countless routine, negotiated agreements which benefit everyone and are happily followed.

But in the long term, such restrictions are likely to accelerate technical self-sufficiency, https://www.theregister.com/2022/07/22/china_smic_7nm_chips/
