Investors are digesting Trump's stiff tariffs on imports from more than a dozen countries and delayed the return of sweeping April levies.

Asian stocks were higher while European stocks and U.S. futures were mostly flat as markets focus on the latest trade developments after President Trump announced a three-week extension to the tariff deadline to Aug.

All three major U.S. indexes ended higher last week, notching three record closing highs despite an abbreviated trading week.
