Wakhan Corridor in the context of "Pakistan"

Tajikistan, officially the Republic of Tajikistan, is a landlocked country in Central Asia. Dushanbe is its capital and most populous city. Tajikistan borders Afghanistan to the south, Uzbekistan to the west, Kyrgyzstan to the north, and China to the east and is narrowly separated from Pakistan by Afghanistan's Wakhan Corridor. It has a population of more than 10.7 million people.

The territory was previously home to cultures of the Neolithic and the Bronze Age, including the Oxus civilisation in west, with the Indo-Iranians arriving during the Andronovo culture. Parts of country were part of the Sogdian and Bactrian civilisations, and was ruled by those including the Achaemenids, Alexander the Great, the Greco-Bactrians, the Kushans, the Kidarites and Hephthalites, the First Turkic Khaganate, the Umayyad and Abbasid Caliphates, the Samanid Empire, the Kara-Khanids, Seljuks, Khwarazmians, the Mongols, Timurids and Khanate of Bukhara. The region was later conquered by the Russian Empire, before becoming part of the Soviet Union. Within the Soviet Union, the country's borders were drawn when it was part of Uzbekistan as an autonomous republic before becoming a constituent republic of the Soviet Union on 5 December 1929.

The Durand Line, also known as the Afghanistan–Pakistan border, is a 2,640-kilometre (1,640 mi) international border between Afghanistan and Pakistan. India also claims a land border with Afghanistan, on the eastern end of the Durand Line, between Afghanistan's Wakhan Corridor and Gilgit, administered by Pakistan but also claimed by India as part of the disputed Kashmir region. The western end runs to the border with Iran and the eastern end to the border with China.

The Durand Line was established in 1893 as the international border between the Emirate of Afghanistan and the British Indian Empire by Mortimer Durand, a British diplomat of the Indian Civil Service, and Abdur Rahman Khan, the Emir of Afghanistan, to fix the limit of their respective spheres of influence and improve diplomatic relations and trade. Britain considered Afghanistan to be an independent state at the time, although they controlled its foreign affairs and diplomatic relations.

The Afghanistan–Tajikistan border is 1,357 km (843 mi) in length and runs from the tripoint with Uzbekistan in the west to the tripoint with the Xinjiang region of China in the east, almost entirely along the Amu Darya, Pyanj and Pamir Rivers, except for the easternmost section along the Wakhan Corridor and divides the ethnic Tajik community into citizens of two separate countries.

The Afghanistan–China border is a 92-kilometre-long (57 mi) boundary between Afghanistan and China, beginning at the tripoint of both countries with the Pakistan's federally administered territory of Gilgit-Baltistan, following the watershed along the Mustagh Range, and ending at the tripoint with Tajikistan. This short border is in the far northeast of Afghanistan, distant from much of the country or urban areas in either country, at the end of the long, narrow Wakhan Corridor. The Chinese side of the border is in the Chalachigu Valley. The border is crossed by several mountain passes, including Wakhjir Pass in the south and Tegermansu Pass in the north.

Both sides of the border are protected areas: Wakhan National Park in Wakhan District, Badakhshan Province on the Afghan side and Taxkorgan Nature Reserve in Taxkorgan Tajik Autonomous County, Kashgar Prefecture, Xinjiang Uygur Autonomous Region on the Chinese side.

The Karakoram (/ˌkɑːrəˈkɔːrəm, ˌkær-/) is a mountain range in Asia located primarily in the Kashmir region. The range spans the borders of Pakistan, China, and India, with the north-western extremities of the range extending into Afghanistan and Tajikistan. The Karakoram contains four of the fourteen eight-thousanders, the highest of which is K2, the second highest mountain on Earth.

The Karakoram begins in the Wakhan Corridor in western Afghanistan and extends eastwards into Indian-administered Ladakh and Chinese-administered Aksai Chin, as well as the Chinese province of Xinjiang. Most of the Karakoram is located within the Pakistani-administered Gilgit-Baltistan region. The Karakoram is bounded on the east by the Aksai Chin plateau, on the north-east by the edge of the Tibetan Plateau, and on the north by the river valleys of the Yarkand and Karakash rivers, beyond which lie the Kunlun Mountains. At the north-west corner are the Pamir Mountains. The southern boundary of the Karakoram is formed west to east by the Gilgit, Indus, and Shyok rivers, which separate the range from the north-western end of the Himalaya. These rivers flow north-west before making an abrupt turn south-westwards towards the plains of Pakistan. Roughly in the middle of the Karakoram range is the Karakoram Pass, which was part of a now unused trade route between Ladakh and Yarkand.

The Pamir Mountains are a range of mountains between Central Asia and South Asia. They are located at a junction with other notable mountains, namely the Tian Shan, the Karakoram, the Kunlun, the Hindu Kush, and the Himalayas. They are among the world's highest mountains.

Much of the range lies in the Gorno-Badakhshan region of Tajikistan. Spanning the border parts of four countries, to the south, they border the Hindu Kush mountains along Afghanistan's Wakhan Corridor in Badakhshan Province, Chitral and Gilgit-Baltistan regions of Pakistan. To the north, they join the Tian Shan mountains along the Alay Valley of Kyrgyzstan. To the east, they extend to the range that includes China's Kongur Tagh, in the "Eastern Pamirs", separated by the Yarkand valley from the Kunlun Mountains.

Badakhshan (Dari: ولایت بدخشان, romanized: Wilāyat-e Badakhshān and Pashto: د بدخشان ولایت, romanized: Da Badakhshān Wilāyat) is one of the northeastern provinces of Afghanistan and is widely regarded as one of the country's most geographically distinctive and historically significant regions. It borders Tajikistan's Gorno-Badakhshan province to the north, China's Xinjiang province to the east, and Pakistan's northern provinces to the south, while internally it neighbors the Afghan provinces of Takhar and Panjshir. The provincial capital is Fayzabad, which functions as the main administrative, economic, and cultural center of the province.

Covering an area of approximately 44,000 square kilometers and having an estimated population of about 1.2 million people (as of 2025), Badakhshan is defined by its mountainous terrain, dominated by the Hindu Kush and Pamir mountain ranges, as well as by deep river valleys shaped primarily by the Kokcha and Panj rivers. The province includes the Wakhan Corridor, a narrow high-altitude strip that extends eastward between Tajikistan and Pakistan to China, giving Badakhshan a unique geopolitical position as Afghanistan's only land connection to China.
