President Trump agreed to delay tariffs on Mexico and Canada for a month after both countries pledged to do more to block drugs and migrants.

Ms Sheinbaum (pictured) won praise at home and abroad for her handling of her mercurial American counterpart. Throughout the confrontation her demeanour was respectful but firm.
