EVIAN-LES-BAINS, France (AP) — The United States could soon reimpose sanctions on Russian oil shipments after President Donald Trump and fellow leaders at the Group of Seven summit of major industrialized democracies moved Tuesday to put the war in Ukraine back on top of their agenda, more than four years after Russia launched its full-scale invasion.

The Iran war has recently overshadowed Ukraine, but Trump said he wants to shift the focus following the announcement of an agreement to end the 3 1/2-month-old conflict in the Gulf.

Trump said Iran will soon be "back in the rearview mirror."

Trump said the sanctions on Russia that were eased during the Iran war to help lower oil prices can go back in place as more oil moves through the Strait of Hormuz.
