Leaders of the Group of Seven industrialized nations are to open a summit in France's Biarritz on Saturday, expected to come up with practical solutions to crises that are shaking the world from the trade war to Iran and the Amazon fires.

The agenda of the summit, which is a club of the world's most industrialized countries (Germany, Canada, the United States, France, Italy, Japan and the United Kingdom), includes international trade and climate issues.

The summit is dominated by many disagreements among member states, particularly over Iran's nuclear dossier, Brexit and the trade war between the United States and China.

The massive Amazon forest fires imposed themselves at the last minute as a major issue on the agenda on the first day of the summit, as sometimes happens in some international meetings.

The environmental disaster will be on the agenda at the dinner, which will be attended by French and American Presidents Emmanuel Macron and Donald Trump, German Chancellor Angela Merkel, British Prime Ministers Boris Johnson, Italian Giuseppe Conte, Japanese Shinzo Abe and Canadian Justin Trudeau.

The French presidency announced Friday that "practical initiatives" to combat fires "can be achieved" during the summit, calling for making this "international crisis" a priority for the summit.

The discussions could be sensitive after Macron accused Brazilian President Jair Bolsonaro of "lying" about his climate pledges and of "not acting" in the face of the fires that have been devastating since the days of the "world lung."

Macron's criticism has angered Trump, who is Bolsonaro's leading international supporter, and has levied tariffs on French wine imports in response to French charges on US technology giants.

For its part, Berlin expressed reservations after Paris announced it would block a draft trade agreement between the South American Common Market (Mercosur) and the European Union, an issue that will be addressed by Macron and Merkel in a bilateral meeting.

Agence France-Presse says the dialogue between the leaders seems to be hot on imposing fees on the Internet giant groups, and the revival of the global economy and trade disputes between Beijing and Washington the day after the exchange of tariffs.

On the Iranian nuclear file, Macron will inform his guests of the contents of his meeting with Iranian Foreign Minister Mohammad Javad Zarif, who saw in an interview with Agence France-Presse that Paris's proposals to resolve the crisis are encouraging.

In the face of these many current issues, French regulators will try to advance other issues such as combating inequality, education in Africa and protecting the oceans.

Organizers hope to reach "concrete initiatives" with invited leaders such as Indian Prime Minister Narendra Modi and heads of six African countries.

Concurrently, anti-globalization and environmental advocacy organizations are holding a counter-summit on the Franco-Spanish border, in which civic organizations, trade unions and leftist groups will participate, to discuss capitalism, climate change and biodiversity.

Organizers expected about 10,000 people to attend, vowing to hold protests and hold several anti-G7 events.
