Divided G7 starts tough summit with trade tensions high on agenda

Upon arrival at Biarritz airport, Johnson also said he would be telling Trump to pull back from a trade war which is already destabilising economic growth around the world.

"I am very worried about the way it's going, the growth of protectionism, of tariffs that we're seeing," he told reporters.

"Trump would not expect any kind of warm welcome in Biarritz. He does not really care much about G7. He is very much defiant to all international bodies in in general, and he knew in the first place that other leaders in the G7 would be very much opposed to him," Remi Bourgeot, an economist and associate fellow at The French Institute for International and Strategic Affairs (IRIS), told Xinhua.
