President Donald Trump arrived in France Saturday morning after an overnight flight from Washington, his arrival preceded by more tit-for-tat tariff action that economists - and most of the other Group of 7 heads - believe is contributing to a global economic slump.

Axar.az reports citing CNN that he's due to attend a dinner for the leaders Saturday evening at the base of a tall white lighthouse planted atop a rocky cliff overlooking elegant Biarritz, the venue for this year's summit. Formal talks begin Sunday morning.

World leaders have plenty to discuss. Festering foreign policy matters like Iran and fresh tensions between India and Pakistan are on the table. The summit's host, French President Emmanuel Macron, says he also wants to address raging wildfires in the Amazon rainforest.

Heading into the summit, however, the flagging global economy appeared the most pressing matter. Trump insisted on a special Sunday morning session to discuss it. Other leaders blame his use of tariffs - on friends and foe alike - for weighing down growth, causing manufacturing to contract and throwing equity markets into turmoil.
