Emmanuel Macron and Donald Trump have agreed to extend negotiations on a row over a French tax on digital giants, postponing Washington's threat of sanctions against Paris, a French diplomatic source said Monday. The source said the French and US presidents, who met on Sunday, had agreed to give negotiations a chance to avoid "a trade war that will benefit no one". Macron tweeted earlier Monday that he had had a "great discussion" with Trump on the issue. "We will work together on a good agreement to avoid tariff escalation," he said. jri/ib/klm/dl
