Depends on whether you want to be in it. A ladder might be enough to peek over the top and rip it off. Do it better. Which seems to be what is happening.
That only works for China's domestic market. As long as the IP they are "taking inspiration from" is protected in the target markets, they effectively lock themselves out by doing that.
In the case of technology like RISC, pretty much all the value add is unprotected, so they can sell those products in the US/EU without issue.
