In believing that the dairy industry could improve the living standard and nutrition standard of citizens and thereby promote rural economic development and compensate food inadequacy, Wei-Chuan established the dairy product department in the beginning of the 1960s out of the company's insistence on establishing a “public company”.

Today, the founder Huang Lieh-ho was also called the “Father of the dairy industry” in Taiwan for this reason.

In 1998, Ting Hsin International Group became the largest (40%) shareholder following an ownership and management fight within the founding Huang family.

One of the joint ventures, Formosa Flexible Packaging, was moved back to Hotai Motor Group.

The Wei-Chuan USA division was founded in 1972 and operates manufacturing and distribution centers in Jersey City, Los Angeles, San Francisco, Chicago, Atlanta, Houston, and Tennessee.
