On display are fifty photos, depicting the beauty of Ha Long Bay, and its potential for tourism, bio-diversity and plentiful flora and fauna.

At the opening ceremony, Bui The Giang, Ambassador and Deputy Permanent Representative of Vietnam to the UN, stated that the beauty of Ha Long dazzles not only Vietnamese but also foreign friends, including Americans.

The exhibition will last until Aug. 18 as convincing proof of the fine development of bilateral relations between Vietnamese and American people.

The final voting stage for world natural wonders will take place between 2010 and 2011.
