A 5 million USD construction materials plant has opened in Cambodia 's Sihanoukville province with Vietnam as an investor.

The plant is financed by Vinacomin Reththy, a joint venture between the Vietnam National Coal and Mineral Industries Group (Vinacomin), Au Viet Industry Joint Stock Co and Cambodian group Mong Reththy.

The plant will provide 80 million products in the first phase using modern brick-making technology which has little impact on environment.

At the plant's opening on June 18, Cambodian Deputy Prime Minister Kiet Chun said the project would help foster economic development and job creation in the area.

Vietnamese Deputy Minister of Industry and Trade Le Duong Quang applauded the effort to put the plant into operation ahead of schedule.

Quang, who is also Vinacomin's board chairman, said the project was a sign of growing investment ties between the two countries.

Vietnam is Cambodia 's biggest source of foreign investment at 900 million USD./.
