Panj (river) in the context of "Afghanistan–Tajikistan border"

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.

The Parni (/ˈpɑːrnaɪ/; Ancient Greek: Πάρνοι, Parnoi), Aparni (/əˈpɑːrnaɪ/; Ἄπαρνοι, Aparnoi) or Parnians were an East Iranian people who lived around the Ochus (Ancient Greek: Ὧχος Okhos) (Tejen) River, southeast of the Caspian Sea in Central Asia. It is believed that their original homeland may have been what is now southern Russia in Eastern Europe, from where they emigrated with other Scythian tribes. The Parni were one of the three tribes of the Dahae confederacy.

In the middle of the 3rd century BCE, the Parni invaded Parthia, "drove away the Greek satraps, who had then only just acquired independence, and founded a new dynasty", that of the Arsacids.

Khorog (Russian: Хорог [xɐˈrok]), also Khorugh (Tajik: Хоруғ [χɔˈɾuʁ]) or Kharagh (Shughni: Харағ [χɐˈɾaʁ]), is the capital of Gorno-Badakhshan, Tajikistan. It is also the capital of the Shughnon District of Gorno-Badakhshan. It has a population of 30,500 (2020 est.).

Khorog is 2,200 metres (7,200 ft) above sea level in the Pamir Mountains (ancient Mount Imeon) at the confluence of the rivers Ghunt and Panj. The city is bounded to the south (Nivodak) and to the north (Tem) by the deltas of the Shakhdara and Ghunt, respectively. The two rivers merge in the eastern part of the city flow through the city, dividing it almost evenly until its delta in the Panj, on the border with Afghanistan. Khorog is known for its poplar trees that dominate the flora of the city.

The Bartang (Russian and Tajik: Бартанг, Persian: برتنگ) is a river of Central Asia, and is a tributary to the Panj which itself is a tributary to the Amu Darya. In its middle and upper reaches, it is respectively known as the Murghab and Aksu; it flows through the Wakhan in Afghanistan, then through the Rushon District of the Gorno-Badakhshan autonomous region, Tajikistan. The river is 528 kilometres (328 mi) long (133 km excluding Aksu and Murghab) and has a basin area of 24,700 square kilometres (9,500 sq mi).

Langar is a village in the Wakhan District of Badakhshan Province, in north-eastern Afghanistan. It lies on the river Panj, opposite the larger village of Toqakhona in Tajikistan.

The place should not be confused with a seasonal settlement called Langar, also in Wakhan, on the upper Wakhan River, some 130 km east.

Khatlon Region (Tajik: Вилояти Хатлон, romanized: Viloyati Xatlon), one of the four provinces of Tajikistan, is the most populous of the four first-level administrative regions in the country. It is situated in the southwest of the country, between the Hisor (Gissar) Range in the north and the river Panj in the south and borders on Districts under Republican Subordination in the north, on GBAO in the east, on Afghanistan (Balkh, Kunduz, Takhar and Badakhshan provinces) in the southeast and on Uzbekistan (Surxondaryo region)in the west. During Soviet times, Khatlon was divided into Kurgan-Tyube (Qurghonteppa) Oblast (Western Khatlon) – with the Kofarnihon and Vakhsh river valleys – and Kulob Oblast (Eastern Khatlon) – with the Kyzylsu and Yakhsu river valleys. The two regions were merged in November 1992 into today's Khatlon Region (or viloyat/oblast). The capital city is Bokhtar, formerly known as Qurghonteppa and Kurgan-Tyube.

Khatlon has an area of 24,700 square kilometres and consists of 21 districts and 4 district-level cities. The total population of Khatlon in 2020 was 3,348,300, up from 2,677,251 in the 2010 population census. The population in Khatlon is mainly engaged in agriculture.

The Qizilsu (Tajik: Қизилсу) or Kyzylsu (Russian: Кызылсу) is a river that rises on the southern slopes of the Vakhsh Range in the north-east of Tajikistan's Khatlon Region and runs south-west until joining the Panj on the border with Afghanistan. The river is 230 kilometres (140 mi) long and has a basin area of 8,630 square kilometres (3,330 sq mi). It merges with the Yakhsu (Akhshu) as a major left tributary south of the town of Kulob. It irrigates the cotton-growing Qizilsu Valley between Kulob and Panj in the south-east of Khatlon Province. It is not the Kyzyl-Suu River that rises in Kyrgyzstan and flows through Tajikistan as Surkhob, then Vakhsh, following a course north-west of Qizilsu.

Panj (Tajik: Панҷ) is a city in southern Tajikistan which is situated on the Afghan border, some 252 kilometres (157 mi) south of the capital Dushanbe. It is located along the north bank of the river Panj, from which it derives its name. The population of the town is 12,500 (January 2020 estimate).
