Sep. 11, 2017 - China National Building Material (CNBM) and China National Materials Company (Sinoma) have entered into a merger agreement. The exchange ratio has been set at 1 Sinoma share to exchange for 0.85 CNBM share. After the merger is completed Sinoma will be absorbed into CNBM. Merger preparations for the two state-owned companies have been on going since mid-2016 when the Assets Supervision and Administration Commission announced the move.

CNBM is the largest cement company in the country with a reported total production capacity of around 409Mt/yr. Sinoma is a cement engineering company and the fourth largest cement producer in China with a total production capacity of approximately 112Mt/yr. The merger is part of the government's plans to consolidate production domestically and refocus its industries internationally as part of the "One Belt, One Road" initiative.
