US President Donald Trump said on Sunday that there was a progress during talks on the first day of the G7 summit in the French city of Biarritz.

“France and President @EmmanuelMacron have done a really great job thus far with a very important G-7. Lunch with Emmanuel was the best meeting we have yet had. Likewise, evening meeting with World Leaders went very well. Progress being made!” Trump wrote on Twitter.

Before the summit, the French leader invited Trump to an impromptu lunch, during which the parties discussed a number of issues, including trade, tensions in the Persian Gulf, the situation in Libya and Iran.

Meanwhile, US officials in private conversations criticized French President Emanuel Macron for an attempt to put pressure on US President before the summit, the Wall Street Journal reported on Saturday.

According to the publication, a flurry of criticism hit Macron after he had invited Trump to an impromptu lunch, during which the parties discussed a number of issues, including Iran and Amazon wildfires. Such a one-on-one lunch was not planned in advance, the newspaper stressed.

Members of the US presidential administration accused the French president of focusing on such “niche” issues as climate change and the development of Africa, which meet his own political interests, the publication said.

According to a senior French official, the French president used lunch to explain his position on controversial issues, in particular, tensions in world trade.

The Group of Seven (G7) Summit officially opened in the city of Biarritz in southwestern France. More than 13,000 policemen and gendarmes arrived in the region to ensure security at the event.
