Although by reading the history of Vietnam, I have a feeling they'd use a different method than the Tibetans had their country been occupied by China. They'd fight to the last bullet, to the last man, even the last woman and child. They'd still have zero chance against China and their country would be erased from the map of the world just like Tibet, but they sure will not vanish without a fight. The irony of violence from a kammic standpoint! China took Tibet 'cuz they can. They haven't touched Vietnam 'cuz they know Vietnam can't be killed without them losing a few limbs for life first!
