On June 15, President Donald Trump and world leaders from Canada, France, Germany, Italy, Japan, and the United Kingdom will meet in Kananaskis, Canada for the annual Group of Seven (G7) Meeting. 

The 2025 G7 Summit will be an important opportunity for leaders of key Western democracies to resolve current trade issues, establish cooperative strategies for managing the rapid development of technologies such as AI, and address rising tensions with China and Russia.

This G7 meeting will be the 50th meeting of this kind. The first occurred in 1975 in Rambouillet, France. Back then, it was then known as the G6 meeting. Canada was invited a year later. I remember the Rambouillet Summit vividly, because I was fortunate enough to be there.

Having now participated in many Summits, I have come to recognize their value. They seldom produce big breakthroughs, but they can reduce friction, forge common understandings, and set the direction towards progress which larger and more unwieldy institutions cannot. 

But due to the changing global order—specifically, the economic rise of China and countries from the Global South—some have come to question the relevance of the G7 Summit. 

Here’s what the first meetings can teach us about the importance of the G7 meeting ahead and about the G7 as an institution: 

The first G6 meeting 

The Group was designed to unify, and develop common strategies among, the leaders of these countries to address formidable economic problems they faced at the time. For instance, each was recovering then from the 1973 OPEC oil embargo aimed at Western nations that had supported Israel in the 1973 War.

They were also adjusting to the recent collapse of the Bretton Woods Monetary System,  which saw the U.S. cease convertibility of the dollar into gold and impose a 10% tariff as leverage to compel other industrialized countries to reduce America's trade deficit. (This came to be known as “the Nixon Shock,” and was a source of considerable friction between the U.S. and its allies.)

At the time, most of these........
