The US will not go to war with China for the simple reason they fear them. China is a smart country, give them points for that. China knows how and where to make its plays. The US doesn't have the military or political power to fight China. The US is a very war experienced country and is trained in fighting long bloody wars as long as the citizens like the wars caused.
The US donesn't have anything against China. Actually, the US and China should be friends... but things aren't like that.
China
China would win. China has more soldiers, bigger armies, better technology, and strong/growing allies.
Without any allies, China would probably win... because of its big number of people and technologies.
There is no way the Vietcong would win against China. China has the biggest army in the world. Give China the win.
The US has the world's most powerful military. USA wins.
China has sheer numbers. You decide. [China because the US relies on China economically and for their military, since the US uses the money China give them to buy military weapons, and they buy weapons from them.]
Then China would probably not win

The u.s would actually win because they are the ones with the tech and strength. Yes China has a big army but they are only low quality. America has more tanks, larger air force and its army is more equipped to deal with China
The US and China are not at war so this question is unanswerable.

It is likely that US might win the war. Russia could defeat both India and China together, but they would get a lot of their soldiers lost in the battle. US has much better weapons and better, trained soldiers than Russia, making it more powerful.
