Just to clarify, celibacy is practised by both East and West, by Orthodox and by Catholics alike.
"Clergy" includes the 3 major orders: episcopate, presbyterate, and diaconate.
East and West have celibate episcopate.
Both traditions have married and unmarried diaconate.
On the presbyterate, East and West have celibate monastics and those belonging to religious orders, if any. (Some Eastern Catholic Churches have religious orders.)
However, it is only on the diocesan priests (parish priests) that we differ. Latin Rite (Roman) Catholics follow the discipline of celibacy for all priests (monastics, religious, and diocesan), with exceptions through pastoral provisions governing married Anglican/Episcopalian clergy converts and by special dispensation for converts of other Protestant married clergy.
In like manner, you Orthodox have the discipline of celibacy for monastics (and religious, if any) but allow optional celibacy for diocesan priests, i.e., they are either married or unmarried. Although majority of Orthodox diocesan priests are married, I believe.
As to the Eastern Rite Catholics (not Eastern Rite RCCs as the RCC is herself a Rite within the Catholic Communion), they are free to follow their Eastern tradition by having married diocesan priests.
However, some Eastern Catholic Churches prefer to ordain the unmarried. The "imposition" of celibacy on the Eastern Catholic Churches in the U.S. has long been rescinded.
It has been documented that currently there are more Latin Rite (Roman) married priests (because of Anglican/Episcopalian and other Protestant converts) than Eastern Catholic married priests in the U.S.
