UK Foreign Secretary and First Secretary of State Dominic Raab said the UK-US relationship is secure no matter who wins the US presidential election.

German Foreign Minister Heiko Maas urged US politicians to maintain trust in the electoral system, after President Trump prematurely declared victory in the tightly contested race.

Mexican President Andres Manuel Lopez Obrador said he will not comment on the election until a final result is announced, adding that he is pleased that the US election has had no effect on the Peso-dollar exchange rate.
