AANES–Syria relations concern the military and political relations between the Ba'athist Syrian Arab Republic and the Autonomous Administration of North and East Syria (NES), a de facto autonomous multi-ethnic region in northern and eastern Syria. The Syrian government does not officially recognise the autonomy of the AANES, and advocates a centralist approach to the governance of Syria. The NES seeks the federalisation of Syria. For most of the Syrian civil war, there has been a non-aggression pact between the military of Syria and the Syrian Democratic Forces, with occasional confrontations and some cooperation against Islamist groups, in particular against the Turkish Armed Forces and the Turkish-backed Syrian National Army.
