Kazakhstan–Uzbekistan relations refers to the relations between the neighbouring Republic of Kazakhstan and Republic of Uzbekistan. The last President of Uzbekistan Islam Karimov has visited Kazakhstan several times.
Both Kazakhstan and Uzbekistan were part of the Soviet Union before its official dissolution in 1991. At the start of the 21st century, 96% of the international border between Uzbekistan and Kazakhstan had been determined. In 2001, after mutual agreements, the border line in only three disputed areas (Bagys, Arnasai and Nsan) remained undrawn. By September 2002, Kazakhstan and Uzbekistan had fully resolved the course of their 2,440km-long shared border.
On 19 October 2006, Kazakhstan built 45km-long barrier along part of its border with Uzbekistan. The Kazakhstan–Uzbekistan barrier spans the Saryagash and Maktaaral administrative districts of southern Kazakhstan, and consists of a 2,5m-high barbed wire fence that includes searchlights. The barrier is situated along the heavily populated towns and cities of eastern Uzbekistan. It was built to curb drug smuggling across the border.
