Let U˜ ı be a quasi-split universal ı quantum group associated to a quantum symmetric pair (U˜, U˜ ı) of Kac-Moody type with a diagram involution τ. We establish the Serre-Lusztig relations for U˜ ı associated to a simple root i such that i≠ τ i, complementary to the Serre-Lusztig relations associated to i= τ i which we obtained earlier. A conjecture on braid group symmetries on U˜ ı associated to i disjoint from τi is formulated.
