Future accelerator neutrino experiments will provide a powerful tool to measure standard oscillation parameters and search for new physics. In this context, we discuss the prospects of building an accelerator neutrino experiment in China. The feasibility of such facilities is investigated by evaluating their prospects to the standard mixing parameters. As an example, we consider an SPPC-based neutrino beamline and CJPL-based neutrino detector with 1736~km baseline length. We find this setup able to significantly improve the precision on $\delta_{CP}$, $\theta_{23}$ and $\Delta m_{31}^2$.
