I've compared this vase to other peach vases online. I am thinking republic but it could be later or sooner.
I think the peach tree pattern was used since the Yongzheng period. Your vase looks 20th Century to me, probably early PROC at the earliest, but can't be sure without seeing the base.

20th century on the later side in my opinion, there would normally be 13 peaches and the decoration looks newer than antique or vintage.
