between them. In 1873 Britain and Russia agreed on a rough formulation of the border, with the Amu Darya declared to be the border going east from the vicinity of the village of Khwaja Salar to Lake Zorku, with the Wakhan Corridor to remain in Afghanistan. The western section of the border (i.e. the bulk of the modern Afghan-Turkmen boundary) was to be determined at a later date by a boundary commission. Tensions mounted as the Russians expanded further into what is now Turkmenistan in the early 1880s, reaching a crisis with the Panjdeh incident (near Sandykachi in what is now Turkmenistan), an area claimed by Afghanistan. Discussions calmed the situation and a joint Anglo-Russian boundary commission demarcated the boundary as it is today over the period 1885–88. As the village of Khwaja Salar could no longer be identified it was agreed that the boundary should meet the Amu Darya in the vicinity of Khamiab, Afghanistan. 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 the Amu Darya. This agreement also stipulated the position of the land border in the section east of Lake Zorkul up to China, with a series of boundary pillars subsequently erected. 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." However this treaty was never implemented, and was explicitly annulled by the Frontier Agreement of 1946, which kept the boundary as it was, with riverine islands to be subsequently allocated by a joint commission. In 1979 Soviet troops of the 40th Army crossed the border at Ymamnazar/Kushka as part of the
