evidence: The most sensitive areas of the border are where Soviet infrastructure projects were later split, such as the dam of the Kasansay Water Reservoir. This reservoir sits on the territory of today’s Kyrgyz Republic but was originally financed by the Uzbek Soviet Socialist Republic and was meant to irrigate farmland in today’s Uzbekistan. Most recently, the site hosted a tense military standoff in the spring of 2016 after Kyrgyzstan refused to admit a group of Uzbek engineers to do repair work. Later, in August of the same year, Uzbek police arrested a group of four Kyrgyz workers operating a telecommunications antenna on the summit of the disputed Ungar-Too mountain and detained them for 16 days.
