I’m sorry, I was wrong. I think you are referring to the ceasefire in 2021. Ceasefires are conditional though. Meaning, if conditions change, conflict can restart. And either side can decide. There have been many ceasefires in this conflict.
Cease-fire
Unlike declarations of a cessation of hostilities or a truce, a cease-fire is generally meant to be binding. Like a cessation of hostilities or truce, it is only temporary in nature, but is generally expected to last for a longer period of time.
Cease-fires do not announce the end of a conflict, but they are meant to put the opposing parties in communication with one another about potential permanent settlements.
Unlike a truce, a humanitarian pause or a cessation of hostilities, the declaration of a cease-fire often applies to the entire geographical area of a conflict, according to the UN. Source
