The Khunjerab Pass serves as a vital international border crossing between Pakistan and China. Located at a high altitude in the Karakoram Mountains, it is renowned as the highest paved international border crossing globally. This pass is an integral part of the Karakoram Highway, facilitating significant trade, tourism, and strategic connectivity between the two nations.
- India shares a border with Pakistan to the east, not through Khunjerab.
- Afghanistan borders Pakistan to the west.
- Iran shares a border with Pakistan to the southwest.
