The Ministry of Industry and Information Technology (MII) has requested that China Mobile, China Unicom and China Telecom jointly construct core passive infrastructure with the aim of increasing investment efficiency. In a statement the regulator said it would set up a task force, made up of officials from the MII, the state-owned Assets Supervision and Administration Commission and the three operators themselves, to implement the scheme. The ministry said that the operators’ existing base station towers and ducts which link base station controllers and the base stations must be open for sharing. The operators must also cooperate on building any new towers and ducts in the future. No duplicated construction of such infrastructure will be allowed in any location, unless given prior approval from the provincial authorities.
