China’s stainless steel giant Tsingshan just scored a major deal in Seoul, taking control of POSCO’s key Chinese production assets. The agreement covers two critical subsidiaries: Zhangjiagang Stainless Steel and Qingdao Pohang Stainless Steel.

First on the ground: Tsingshan’s management team moves into the Zhangjiagang facility on July 9, 2025 – marking the start of operational control. This JV has historically been majority-owned by POSCO (82.5%), with China’s Shagang Group holding the remaining stake.

The Qingdao operation presents a unique ownership chain: POSCO holds 80% directly, while the remaining 20% stays with POSCO Zhangjiagang. This facility specializes in cold-rolled stainless production and distribution.

Why this matters:

1. Market consolidation: Tsingshan strengthens its domestic dominance

2. Foreign exit: POSCO continues retreating from Chinese steel production

3. Supply chain control: Direct access to premium cold-rolled capacity

Industry watchers see this as part of Tsingshan’s vertical integration play – securing high-quality finishing capabilities to complement its massive nickel pig iron operations.
