China takes a longer and less forceful approach: political and economic control are their preferred choices by far.
Wars do not benefit anyone bar the arms manufacturers for the most part.

Wikipedia suggests quite a few less: https://en.wikipedia.org/wiki/List_of_wars_involving_the_Uni... but still a lot.
I believe (but haven't checked) that the USA has started at least one war every year since 1945. This was true in the mid 2000s, it might not be now.
That you managed 3 (or at a push 4) versus a hundred or so is a great comparison in favour of my comment: China does NOT want a war. It's bad for business.
That was true of the US in 1942 against the weaker and smaller countries of Japan and Germany.
In today's world, China is the country with the bigger population of military-age men and the bigger manufacturing capacity, not the US.
Just good old arithmetic.
