The trading firm grew to become the present-day Samsung C&T Corporation. But after some years Cho and Lee parted ways due to some differences in management between the two men. He wanted to get up to a 30% group share. After settlement, Samsung Group was separated into Samsung Group and Hyosung Group, Hankook Tire ...etc.
The Second Partition : 1990s
After founder's death,Samsung Group was separated into Samsung Group and three other conglomerates - Shinsegae Group, CJ Group and Hansol Group. Shinsegae(discount store, department store) was originally part of Samsung Group, separated in the 1990s from the Samsung Group along with CJ Group (Food/Chemicals/Entertainment/logistics) and the Hansol Group (Paper/Telecom). The brand-new Shinsengae Centumcity Department Store is now officially recognized by Guinness World Records as the largest department store in the world. Todays these separated groups are independence group and they are not part of or connected to the Samsung Group. One Hansol Group representative said, "Only people ignorant of the laws governing the business world could believe something so absurd," adding, "When Hansol separated from the Samsung Group in 1991, it severed all payment guarantees and share-holding ties with Samsung affiliates." One Hansol Group source asserted, "Hansol, Shinsegae, and CJ have been under independent management since their respective separations from the Samsung Group." One Shinsegae Department Store executive director said, "Shinsegae has no payment guarantees associated with the Samsung Group.
