Siam Cement Group (SCG) will invest US$200m to expand its operations in Cambodia between 2016-20.

The company will focus on the cement and building materials sectors, which have strong potential to grow amid the Cambodian government's policy of ramping up infrastructure projects, said Kan Trakukhoon,  president and CEO of SCG.

"SCG sees Cambodia as one of the more interesting Asean members, with a high economic growth rate," Mr Trakulhoon said.
