Ai Nam Quan is forever lost. The saying that "Vietnamese territory stretches from the Ca Mau point (in the south) to Ai Nam Quan (in the north)" is no longer true. This band of thugs currently in government has sold it to the chinese in order to gain material benefits and strengthening their position to further rape and pillage the Vietnamese people.
Ai Nam Quan's location according to the pre-1954 French map is approx. 8 kilometers from Dong Dang.
This has been reduced to less than 6 kilometers during the Vietnam War. The communist government ceded the Ai Nam Quan strategic pass to the Chinese in order for them to receive chinese support for the war, a war to kill their own people and enslave them under communism. Pham Van Dong also signed an agreement recognizing China's sovereignty over Hoang Sa (the Paracels) and Truong Sa (the Spratleys) islands.
After the 1999 agreement of which this bastardized government again selling Vietnamese territory to china, Dong Dang is a mere 2 km from the border. Also, the border has inched closer to the National Highway 4A.
How would this communist government repay for the crimes it committed against the Vietnamese people and the Motherland?
