  We study spatial isovector meson correlators in $N_f=2$ QCD with dynamical
domain-wall fermions on $32^3\times 8$ lattices at temperatures $T=220-380$
MeV. We measure the correlators of spin-one ($J=1$) operators including vector,
axial-vector, tensor and axial-tensor. Restoration of chiral $U(1)_A$ and
$SU(2)_L \times SU(2)_R$ symmetries of QCD implies degeneracies in
vector--axial-vector ($SU(2)_L \times SU(2)_R$) and tensor--axial-tensor
($U(1)_A$) pairs, which are indeed observed at temperatures above $T_c$.
Moreover, we observe an approximate degeneracy of all $J=1$ correlators with
increasing temperature. This approximate degeneracy suggests emergent
$SU(2)_{CS}$ and $SU(4)$ symmeries at high temperatures, that mix left- and
right-handed quarks.
