2nd G7 summit

The 2nd G7 Summit was held at Dorado, Puerto Rico, between June 27 and 28, 1976. The venue for the summit meetings was the Dorado Beach Resort, which is near San Juan, Puerto Rico.
The Group of Six (G6) was an unofficial forum which brought together the heads of the richest industrialized countries: France, West Germany, Italy, Japan, the United Kingdom and the United States; and the Group of Seven (G7), meeting for the first time this year, is formed with the addition of Canada. This summit, and the others which would follow, were not meant to be linked formally with wider international institutions; and in fact, a kind of frustrated rebellion against the stiff formality of other international meetings was an element in the genesis of cooperation between France's President and West Germany's Chancellor as they conceived the first summit of the G6.
Leaders at the summit.
The G7 is an unofficial annual forum for the leaders of Canada, France, West Germany, Italy, Japan, the United Kingdom and the United States.
The 2nd G7 summit was the first summit for British Prime Minister James Callaghan and, as it was formed with the addition of Canada, Canadian Prime Minister Pierre Trudeau. It was also the last summit for Italian Prime Minister Aldo Moro, Japanese Prime Minister Takeo Miki and U.S. President Gerald Ford.
Participants.
These summit participants are the current "core members" of the international forum: Trudeau of Canada had been invited because he had eight years experience. 
Issues.
The summit was intended as a venue for resolving differences among its members. As a practical matter, the summit was also conceived as an opportunity for its members to give each other mutual encouragement in the face of difficult economic decisions.
