Uzbekistan is a secular state, with a presidential  constitutional government in place. Uzbekistan comprises 12 regions (vilayats), Tashkent City and one autonomous republic, Karakalpakstan. While non-governmental human rights organisations have defined Uzbekistan as "an authoritarian state with limited civil rights"., significant reforms by Uzbekistan's second president have been made following the death of dictator Islam Karimov. Owing to these reforms, relations with the neighbouring countries of Kyrgyzstan, Tajikistan and Afghanistan have drastically improved. A United Nations report of 2020 found much progress toward achieving the UN's sustainable development goals.
