The LS Group and LIG Group—both part of South Korea’s influential Pan-LG family of conglomerates— have signed a memorandum of understanding (MOU) to strengthen cooperation across defense, energy, and advanced technology sectors.

A press release said that the agreement, announced March 31, follows a high-profile gathering of Pan-LG leaders at GS Group’s 20th anniversary, underscoring a renewed spirit of unity among the country’s leading business families.

Under the MoU, LS and LIG will collaborate on joint R&D, market analysis, technology and personnel exchanges, and may establish joint ventures to leverage each group’s core strengths. The LS Group, known for its focus on electrics, materials and energy, will bring expertise from subsidiaries such as LS Cable & System and LS Mtron. The LIG Group, whose portfolio includes defense equipment and IT services, is expected to integrate LS’s material and cable technologies into its flagship defense unit, LIG Nex1, which specializes in advanced weapon and command systems.

A joint consultative body will be formed to define detailed cooperation plans and set an execution timeline. The partnership is widely viewed as a strategic move, especially as LS Group faces heightened competition and legal disputes in the cable sector. Recently, Hoban Group, parent of rival Taihan Cable & Solution, acquired a 3% stake in LS Corp., fueling speculation about its intentions amid an ongoing patent and technology theft dispute between Taihan and LS Cable & System.
