Ethnic Cleansing is a policy of rendering an area ethnically homogeneous by using force or intimidation to remove persons of given groups from the area. You seem to be using a commonly cited inaccurate definition of genocide instead of the broader term “ethnic cleansing”, but note that even genocide does not require killing as the means, as it is defined (in the 1948 Genocide Convention) as any combination of one or more of seven different acts (one of which is killing members of the group) when undertaken with the specific intent to destroy the given racial, ethnic, national, or religious group.
