This sentence dates Vietnam’s nationwide general mobilization to the same day China declared its punitive mission complete (6 March 1979). But multiple sources place the mobilization order on 5 March 1979.

A Vietnamese government-linked historical article states that “on March 5, 1979, President Ton Duc Thang signed Decree 29-LCT ordering a nationwide general mobilization.” A U.S. Marine Corps country study likewise says “March 5, 1979, the government issued a General Mobilization Order.”

So the article’s chronology is off by one day: China’s declaration about its mission came on 6 March 1979, while Vietnam’s general mobilization order was issued 5 March 1979.

This sentence misstates how the 1956 reunification elections were supposed to work.

The 1954 Geneva Final Declaration had already laid out the basic framework: general elections were to be held in July 1956, under an international commission, and consultations were to take place between the competent representative authorities of the two Vietnamese zones from 20 July 1955 onward. In other words, the election mechanism was not something that depended on the United States and the Soviet Union later agreeing on a plan.

A U.S. State Department document from 1955 discussing the issue likewise frames the matter as consultations between the Diem government and the Viet Minh, not as a failed U.S.-Soviet negotiation. It says the Diem government was expected to go through with consultations with the Viet Minh and notes that Diem opposed those consultations because South Vietnam did not consider itself bound by the Geneva Accords.

So the obstacle was not that Washington and Moscow failed to agree on an election plan; the Geneva framework already existed, and the dispute centered on whether the Vietnamese parties—especially South Vietnam—would participate in the required consultations and elections.
