Swiss leaders rush to Washington to negotiate tariffs that threaten key Swiss exports to the US.

Switzerland's President Karin Keller-Sutter and Economy Minister Guy Parmelin have rushed to Washington to negotiate a deal to avoid 39% tariffs on Swiss exports to the US, set to take effect Thursday. The high tariff rate has alarmed Swiss industries like watchmaking and chocolate. The US is a key trading partner for Switzerland, which aims to present a more attractive offer to lower the tariffs.
