紅河デルタ
Đông Bắc (literally "Northeast) is the region to the north of the Red River Delta in Vietnam. It is called "Northeast" to distinguish it from the Northwest, but it is actually in the north and northeast of Hanoi, wider than Việt Bắc. The Northeast is one of three sub-regions of Northern Vietnam (the other two sub-regions are the Northwest and the Red River Delta). Sometimes the Northeast includes the Red River Delta.
