An impressive list
China basically has every important weapon type the rest of the world has. Including nukes, but not aircraft carriers (unless I'm mistaken).
Chinese weapons not battle-tested ? If the jets fly, they'll reach a target. I have no doubt the Chinese are as intent on testing and training as any other Air Force, and nobody has ever said that Chinese are dumb.
But all this is rhetoric. We've passed the stage where a major country could declare war on another major country - we all know that such a war will be devastating, maybe to the point of annihilation. China, like Russia, will continue to be treated with the utmost caution so as to not push them too far.
As for the US, who knows what the Orange One will consider is "too far" ?
