(VOVworld) - A dozen of Vietnamese companies along with 10,000 participants of 400 firms from 35 countries around the world are attending the 7^th Build Eco Xpo (BEXASIA) in Singapore from September 1-3. Nguyen Viet Chi, Vietnam’s Trade Counselor to Singapore, said construction materials, particularly float glass and stone sand, are Vietnam’s key export items to Singapore. In the first seven months of the year, Vietnam grossed around 200 million USD in revenue from exporting these products to the market. Many Singaporean companies attending the event have also expressed a keen interest in the real estate market in Vietnam, Chi said. The expo is a leading business forum in the region for construction material producers, construction bidders and designers.
