Partly True
A claim circulating in Korean industry discourse describes an emerging "new Cold War" in the semiconductor sector, pitting a Korea–Japan alliance on materials, parts and equipment against a Russia–China bloc focused on joint production lines. The claim is assessed as Partly True: the general framing of deepening bloc-based alignment in semiconductor supply chains is supported, but specific details of the two alliances remain unconfirmed.
The claim portrays two competing groupings taking shape in the semiconductor industry. On one side, Korea and Japan are described as forming a cooperative framework centered on materials, parts and equipment — the so-called 'sobjang' (소재·부품·장비, materials·parts·equipment) supply chain. On the other side, Russia and China are described as cooperating on production lines, a pairing widely associated with efforts to work around export controls.
The broader context of intensifying technological rivalry between allied export-control regimes and countries seeking to build self-sufficient supply chains is well documented. However, the claim presents this alignment as a formalized, structured confrontation, and the evidence for such a clear-cut two-bloc structure is incomplete.
The claim does not specify the institutional form, scope or official status of either the Korea–Japan materials cooperation or the Russia–China production cooperation. No details are provided on whether these arrangements involve formal agreements, government programs or informal industry coordination. The characterization of a semiconductor "new Cold War" is therefore best read as an interpretive framing of real but uneven trends, rather than a description of confirmed, parallel alliance structures.
The assessment is Partly True.
