Who led the Communist Chinese?
Why is Mao Zedong so significant to the Chinese communist party and what victory did he accomplish in 1949?
What china communist leader used strategic tactics to lure Chinese peasants to the communist red army?
What is was the relationship of north Vietnam with the communist movements led by the soviet unin and china?
The communist super-power's goal was expanding communism; Hanoi was trying to expand communism by attempting to take over the "Republic" of South Vietnam, a non-communist country (nation). North Vietnam was in keeping with communist expansion; which is why the Chinese Communists/USSR supplied Hanoi with war material & training.
It's actually an interesting question. The Chinese government claims to be communist, although their current policies bear little resemblance to communism as it used to be practiced in the USSR or other communist nations. China has a mixed economy, with both communist and capitalist elements. A more accurate description of the Chinese government would be that it is a self-perpetuating oligarchy.
