What is the new name of the seven sisters country?

The term "Seven Sisters" traditionally referred to the seven northeastern states of India: Arunachal Pradesh, Assam, Meghalaya, Manipur, Mizoram, Nagaland, and Tripura. However, there hasn’t been a new official name for these states collectively. They continue to be recognized individually by their respective names. Recent discussions may focus on their cultural significance or development, but the term "Seven Sisters" remains widely used.
