You would think so, but historically that's why they never became more than a regional power. Empires for millennia craved trade with China but only the mongols from that region made it all the way to western europe in their invasions.
It is a strength, if their goal is to have a stable and prosperous country long term, and that seems to be what they want. good for them. But nature abhors a vacuum, so there will always be an empire at the top of the food chain. Such empires want to maximize wealth for their people and secure them against threats, that's why invasions and exploitation of weaker countries happens. That game hasn't changed. Friendly relations work, until you need a lot of resources from a country that doesn't want to give it up. Or, like with the US, when they're opening up military bases next to your borders and you need a buffer state. Or, when naval blockades and sanctions are being enforced against your country for not complying with extra-sovereign demands.
History shows that countries content with what they have collapse or weaken very quickly.
China will have a population crisis in a few decades for example, and it won't have the large manufacturing base and its people will be too used to luxuries to go back to slaving for western countries for pennies. Keep in mind that the current china itself is so great and prosperous because of all the invasions it did against western china and satellite states like Vietnam and north Korea (the US isn't special in this regard).
Yes, it can but those poles are expansionist/influential empires not isolationist states. For example, China wants involvement in African development but they don't want any say or interference in local affairs, they can exert influence but they don't want to.
