According to the New7Wonders’ website, Vietnam's Ha Long Bay is among the 28 famous world sites, such as the Dead Sea, Grand Canyon in the US, Angel Falls in Venezuela and Fundy Bay in Canada.

A panel of experts chose the finalists from among the 77 nominees that gained the most votes in an early round of polling. People had suggested 261 landmarks in countries from all over the world.

The panel chaired by Federico Mayor, former chief of UNESCO, the UN Educational, Scientific and Cultural Organization, picked the finalists based on geographical balance, diversity and importance to human life.

High voter participation has been seen in several Asian countries, including India, Bangladesh and Vietnam, as well as from Latin America, according to New7Wonders.

Around 100 million people voted in the selection of the seven man-made wonders in 2007. The winners were the Colosseum, Italy; the Great Wall of China; the Taj Mahal, India; Petra, Jordan; Christ the Redeemer Statue, Brazil; Machu Picchu, Peru; and the Pyramid at Chichen Itza, Mexico.

Choosing world wonders has been a continuing fascination over the centuries. UNESCO keeps updating its list of World Heritage Sites, which now totals 890 places.

The New 7 Wonders campaign aims to promote cultural diversity by supporting, preserving and restoring monuments and natural sites. It relies on private donations and revenue from selling broadcasting rights.
