Jusupov said Kyrgyz officials believe the decision was linked to the July evacuation of more than 400 Uzbek refugees from Kyrgyzstan to Romania. The refugees fled to neighboring Kyrgyzstan after Uzbek troops in May forcibly put down an uprising in the eastern Uzbek city of Andijon.
Tashkent had demanded that some of them be deported back home, where authorities said they were wanted as criminals.
