  We report on the construction of an accurate relativistic chiral
nucleon-nucleon interaction up to the next-to-next-to-leading (NNLO) order. We
compare the so-obtained neutron-proton phaseshifts with the
next-to-next-to-next-to-leading order (N$^3$LO) nonrelativistic ones and we
show that up to $T_\mathrm{lab.}=200$ MeV, the relativistic chiral nuclear
force can describe the PWA93 phaseshifts and inelasticities as well as its
N$^3$LO nonrelativistic counterparts. As a result, the relativistic chiral
nuclear force can be readily used for relativistic ab initio nuclear structure,
reaction, as well astrophysical studies.
