Are you Google, Yahoo or Adobe though?
If you're a very high value target, everybody will attack you. NSA, 8400, Russian and Chinese teams, everybody. If you're just an individual working on their personal business, nobody is burning 0days on you.
I have had my personal Lenovo laptop coopted as part of a bot-net burning my net connection with all kinds of requests to unknown addresses. And this happened after I had it returned from an authorized service-center! Needless to say -that was my last Lenovo laptop.
China is indeed mainly focused internally, but there's no limit to how far they'll go in support of those ends. China attacked Google, Yahoo, Adobe, many others, using a zero-day IE exploit.
Of course they'll use your laptop as part of a botnet, C&C proxy, ransomware vector, etc. There's no benefit of the doubt remaining.
