Its greater then their headline spending numbers. If you adjust for purchasing power there is even a bigger difference then their official numbers. But its still less than the US's spending (although something like 85 or 90 percent instead of a much smaller fraction. Perhaps the numbers should be adjusted by a bit less than purchasing power parity (the difference between costs for high tech, or even more mundane military items isn't likely to be the same as it is for civilian production, and at least for the more advanced items is likely to be less), but even then you still get well over half, and China's spending is growing faster, and at least at the moment (and probably at least for the next couple of decades) any conflict would likely happen nearer to China, where China has almost all its forces while American forces are spread across the world with the largest portion in the relatively distant North America.

The main counterbalancing advantages for the US are

1 - The US has more built up capability from previous spending. (But military equipment is a depreciating asset, not a productive investment so the importance of this declines over time).

2 - The US is more likely to have allies on its side.

3 - The US has some geographical advantages. China has to get past potentially hostile countries in the first (and depending on the scenario 2nd) island chains. Also its easier to interdict shipping to China (at least with a distant blockade, a close blockade would be too costly) than it is to the US.

4 - (This one is weaker and less certain) China would probably be seen as the aggressor and get a more hostile world reaction then the US would. The US isn't going to invade China, or just start lobbing missiles at if for the lols. A war with China would most likely start over a Chinese attack of Taiwan, and the other scenarios mostly involve China grabbing disputed territory as well. If China doesn't make such an attack there won't be any war.
