Salamat Alamanov, the Kyrgyz goverment official in charge of regional affairs, told RFE/RL that topographical engineers from both countries have agreed on additional kilometers of the disputed border.
"As a result of consultations conducted at the level of experts, about 2.5 kilometers of the Kyrgyz-Uzbek border have been defined," he said. "Those results have now to be discussed at the level of [government] delegations. They will then be sent to the governments [of both countries] for approval."
Uzbekistan and Kyrgyzstan share a 1,375-kilometer border.
The 300 kilometers or so that remain in dispute have led to a number of border incidents.
Kyrgyzstan also shares common borders with China, Kazakhstan, and Tajikistan. China is the only country with which it has no border disputes.
