Thailand's Siam Cement Group plans to expand its operations in Vietnam, especially in the cement and  petrochemical sectors.

"Our target is that we must have a cement factory here, but by when we still cannot say. We're studying if we should invest on our own or through a joint venture," Dhep Vongvanich, SCG's Vietnam executive director, told The Nation newspaper.

Meanwhile, Vongvanich added that SCG would continue with the construction of the US$4.5bn Long Son integrated petrochemical complex in the southern Ba Ria – Vung Tau Province, despite the recent withdrawal of Qatar Petroleum, one of the four key partners in the project.
