The bright spatial solitons in nonlocal defocusing Kerr media with parity-time () symmetric potentials are studied. The influence of the degree of nonlocality on the solitons and the transverse energy flow within the stable solitons are examined. We also find that these solitons can exist and be stable over a different range of the propagation constant and potential parameters. Interestingly, there exists a threshold value for the degree of nonlocality or potential parameters.
