LONDON (Reuters) - British Foreign Secretary Boris Johnson told his Russian counterpart Sergei Lavrov on Thursday that the two countries needed to build a constructive relationship despite their significant differences.

"The Foreign Secretary made clear that while we have some significant differences with Russia, we need to continue to build a constructive dialogue on issues of mutual concern as well as on points of disagreement," a Foreign Office statement said after the two men spoke by telephone.

Earlier, the Russian Foreign Ministry said Johnson and Lavrov had discussed a possible normalization of bilateral ties.
