DKSH, also known as DiethelmKellerSiberHegner, is a Swiss holding company specialising in market expansion services, e.g.

[7] Although its headquarters is in Zurich, DKSH is deeply rooted in communities all across the Asia Pacific region.

Independently and within a few years of each other, Hermann Siber set off for the Japanese port of Yokohama, Wilhelm Heinrich Diethelm for Singapore, and Eduard Anton Keller for the Philippines.

[10] In 1868, Eduard Anton Keller joined C. Lutz & Co., which was founded in Manila in 1866, and renamed this existing enterprise Ed.

Although the European market played a subsidiary role, each headquarters was situated in Switzerland, which illustrates the intensive contact with the home country.

Established in 1906 on the banks of Chao Phraya River, today the company is one of Thailand's leading business organizations, with annual sales of THB 114 billion in 2022.

[19] With several acquisitions in Australia and New Zealand between 2018 and 2020, DKSH has strengthened both the services' portfolio and its geographical market coverage in the Pacific region.
