Abstract We study the dynamics of two-dimensional spatial solitons supported by partially-parity-time (

P P T

)-symmetric optical Bessel lattices. We show that these solitons with an imposed tilt can follow an oscillating or even a whole rotary trajectory in the transverse plane guided by a Bessel optical lattice. Due to the complex optical potential, these rotary solitons can also suffer from amplification or attenuation. Interestingly, we found that it is possible to find quasi-stability regions of parameters where there is a balance between the imposed tilt and the

P P T

-symmetric potential, allowing the launched spatial dissipative solitons to complete several rotations in their propagation.
