Leaders of some of the world’s biggest economic powers will arrive in the Canadian Rockies on Sunday for a Group of Seven summit overshadowed by a widening war across the Middle East and U.S. President Donald Trump’s unresolved trade war with allies and rivals alike.

Diplomats said Canada has ditched the idea of a traditional joint communiqué and would issue chair summaries in hopes of containing a disaster and maintaining engagement with the U.S.

Trump's first multilateral summit of his second term, the G7, comes amid the backdrop of Israel and Iran on the brink of war, and tariffs.
