China, Russia, Vietnam.
Japan left Vietnam because the US won the Vietnam War. The US effectively kicked them out of the area. This was preventing China from invading Vietnam as well.
Most definitely. Simply had to invade North Vietnam. If the Soviets or Red China intervened; use nuclear weapons against them. Which is why North Vietnam wasn't invaded.
China and Vietnam
Vietnam is very skilled at ambushing and attacking. This will guaranteed that Vietnam is stronger than China because Vietnam's military soldiers have AK-47's and better Su-27 aircraft and other planes. China has never won a war against Vietnam before, therefor Vietnam will win the war against China. Vietnam is a very poor small country but is still very strong. Vietnam has defeated Mongolia before. Mongolia is not stronger than Vietnam because Vietnam has a better army. Vietnam defeated Mongolia thousands of years ago however Mongolia has never beat Vietnam before. but Mongolia will still never win a war against Vietnam. Vietnam is stronger.
