So China is just claiming that anyone who is ethnically Chinese should be pressured? Manus is in Singapore and has no direct connections to China physically and financially. SG offices, SG product, SG founders with family on the mainland.
Manus started in China, built by Chinese talent, hence all their work under purview of PRC export control laws, PRC merely closing loophole on SG washing. They haven't even done nuclear option like banning PRC from working in US AI like US has done in PRC semi.
1. Not SG founders
2. China already claims jurisdictional reach on anyone (chinese national or not) when their national interest is involved.
