Three Pillars, One State

The 1998 restructuring strategically overhauled China’s petroleum sector, forging the integrated “Three Pillars” of CNPC, Sinopec, and CNOOC. This reform addressed chronic inefficiencies by stripping administrative functions from corporations and executing a landmark asset swap: CNPC gained downstream assets to dominate the north, while Sinopec acquired upstream operations to lead the south, each becoming vertically integrated giants. CNOOC remained the dedicated offshore pillar. This created a tripod of national energy sovereignty. Decades later, the framework underpins China’s security. In 2025, the three pillars produced 97% of China’s total 216 million tons of crude oil. Sinopec added massive new reserves, while CNPC contributed nearly half of domestic production. The restructuring was the foundational moment that forged the modern, globally competitive entities acting as the primary engines of China’s energy supply and industrial policy.
