Afghanistan–Tajikistan border

[7] The easternmost section of the border (now forming part of the Afghan-Tajik boundary) was not finally delimited until 1893–95, with the Afghans agreeing to waive any claims to lands north of the Amu Darya.

This agreement also stipulated the position of the land border in section east of Lake Zorkul up to China, with a series of boundary pillars subsequently erected.

[7] In 1921, a Soviet-Afghan treaty was signed whereby Russia agreed "to hand over to Afghanistan the frontier districts which belonged to the latter in the last century, observing the principles of justice and self-determination of the population inhabiting the same."

Security improved with the end of the Tajik war and the fall of the Taliban government in 2001; however the long, porous frontier remains poorly policed and is a major drug smuggling route.

[10] Several new border crossing and bridges have built in recent years in an effort to boost trade and links, partly funded by foreign governments and the Aga Khan Development Network.
