Non-recognition

Non-recognition is the practice and legal obligation not to extend diplomatic recognition to annexations or de facto states created through violation of international law. It is a counterpart to the rejection of right of conquest in modern international law and the jus cogens norm of prohibition on the acquisition of territory through force.{{cite book |last1=Talmon |first1=Stefan |date=2006 |pages=99–125 |chapter=The Duty Not to ‘Recognize as Lawful’ a Situation Created by the Illegal Use of Force or Other Serious Breaches of a Jus Cogens Obligation: an Obligation without Real Substance? |title=The Fundamental Rules of the International Legal Order: "jus Cogens" and Obligations "erga Omnes" : [Berlin Workshop] |publisher=BRILL |isbn=978-90-04-14981-6 |language=en}}{{cite journal |last1=Azarova |first1=Valentina|authorlink=Valentina Azarova (academic) |title=The secret life of non-recognition: EU-Israel relations and the obligation of non-recognition in international law |journal=Global Affairs |date=2018 |volume=4 |issue=1 |pages=23–37 |doi=10.1080/23340460.2018.1507278|s2cid=158794287 }}{{cite journal |last1=Grant |first1=Thomas D. |title=East Timor, the U.N.
