No they don’t. That’s like overhyping the Sunni-Shi’ite divide among Muslims. Communism is all about internationalism and spreading the revolution. The Mafia politics among leaders is no display of disunity as far as the ideology goes.
Even Putin himself said that Lenin destroyed the Soviet Union, Communism is over. The old farts in Vietnam just want to keep their jobs, they are Communist in Name Only. A lot of foreign corporations, like Nike have factories in Vietnam.
Economic systems are much different in the South such as in Saigon (no one really calls it HCMC) where basic free enterprise is the rule rather than the exception.
Danang is the middle zone, which is a mix of communism and capitalism. There’s tension, mixed with freedom, somewhat.
When you’re in Hanoi, you can feel the state, where the freest traders are the souvenir sellers around Hoan Kiem Lake, and even they owe part of their take to the government.
Old Uncle Ho had expressed in his life that he wanted his ashes spread upon hillsides in the North, the Center and the South. But when he died they mounted his corpse like Lenin, in a Soviet style blockhouse in Hanoi - so oddly out of step with Vietnamese architecture - to be periodically shipped back to Russia for touchups.
He’d come a long way from the Vietnam of post-WWII when Vo Nguyen Giap saluted the American flag with the OSS delegation in Hanoi, when Archemides Patti was cabling to Truman that Ho Chi Minh wanted to work with the Americans. But Truman decided that the French could reenter Vietnam as a colony. And the rest is, as they say, history.
"As for me, I prefer to smell French s--t for five years, rather than Chinese s--t for the rest of my life." - Ho Chi Minh
