At the end of 1862 the Federal Council nominated Aime Humbert (1819-1900) as plenipotentiary minister and charged him with negotiating an agreement with Japan. Almost one year after his arrival in the year 1863 and thanks to the support by the Dutch minister, Dirk Graeff van Poslbroek, Aime Humbert succeeded in concluding an agreement on 6 February 1864. Initially the treaty resulted in numerous, fruitful economic activities by Switzerland which exported arms, watches and precision instruments to Japan and imported valuable silk threads to Switzerland. Trading companies such as Favre-Brandt, Sieber-Hegner, Liebermann-Walchli successfully settled in Yokohama, later in Osaka-Kobe. See "150 Years Bilateral Relations Switzerland-Japan".
