India has officially registered 27 locations in Arunachal Pradesh (a northeastern state that China claims as part of its territory and calls "South Tibet") — including mountain passes, a lake, and a monument — under their standard names on India's official map. Beijing responded sharply, calling the move "self-deception" that undermines improving bilateral ties, while Chinese state media framed it as a unilateral action with no legal effect on the area's status. The dispute is part of a long-running pattern: China has itself issued over 110 standardised names for locations in the region since 2017, and neither side recognises the other's cartographic claims.
