If you include Japan and south Korea...that is simply not so.For building warships, they are insignificant.
But, by using SouthWest you may parse them out. But you cannot prse them out of any caomparison with China, since both of them are directly in the spheres of influence of one another.
Both have built similarly large AEGIS ships...and are capable of building even larger ones.
Certainly not in the numbers the Chinese are now building...but with their mutual defense treaties with the US and other western pacific nations...they do not individually need to.
