Probably China. There are many discussions about this, look online.
The army who would win is Russia because they have a better army. then Russia also has is they got is better weapons.
Russia. They have way more nukes then China.
For North Vietnam to win the war; which they did.

No one. The US, Russia, and China each have sufficient nuclear weapons to lay waste to the entire globe.
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.
It would be a close fight. China has more men to fight with. China also has more reserves. China has unquestionably better navies and air forces when compared to Russia, and around 9 times the amounts of tanks. China has the largest army in human history, more than the entire population of the United States. So, in a short war, China would win. In a longer war, China would win and begin to take Russian lands, eventually scoring the victory.This is of course assuming no nuclear weapons are used. Otherwise, China would also win.Answer:China would win without really trying.
Russia
The US would never fight a conventional war with China or Russia, but might support a country that did (as with Afghanistan from 1979 to 1989). Russia has a much larger conventional army, and China an even larger one. Any armed conflict would likely lead to a nuclear exchange, either limited or total. Russia has parity with the US in nuclear weapons, while China is still a distant 3rd.
China
Russia. Russia could defeat any country except America and China, with or without nukes.
i would say russia because there a very big country
no china has much more men
