Vienna-The latest stab of Donald Trump’s customs Willkür now meets Switzerland. In the middle of the heart. The US President has imposed tariffs of 39 percent through products from Switzerland. How this percentage comes about, this also makes top economists puzzled. That is “difficult to understand,” said Christian Keuschnigg, now economist in the Swiss St. Gallen and formerly head of the Institute for Higher Studies (IHS) in Austria, on Wednesday in the Honey 2. In any case, the height cannot be explained solely by the volume of the United States’ commercial balance sheet deficit with Switzerland.
