Leaders of some of the world’s biggest economic powers will arrive in the Canadian Rockies on Sunday for a Group of Seven summit shadowed by a widening war in the Middle East, and U.S.

The Canadian prime minister said officials in Ottawa and Washington are in intense talks on a new economic-and-security pact, but there is no deal yet.

Global trade will be a major focus at next week’s G7 summit as world leaders gather in Alberta, including U.S. President Donald Trump, who will be making his first appearance at a major international event since returning to the White House in January.
