Initial attempts by Swiss President Karin Keller Sutter to change Trump's mind fell on deaf ears. But a visit on 4 November by business leaders appears to have changed his mind.

Swiss industry chiefs came to the Oval Office on 4 November bearing gifts, including a Rolex gold watch and a specially engraved gold bar from Swiss-based gold refining company MKS.
