Switzerland is casting two plaques of Ha Long Bay in bronze to prepare for the official recognition ceremony of the New Seven Wonders of Nature.

The plaques, 1.2m high and 1m wide, weighing around 100kg each will be sent to Vietnam before the ceremony.

They will be placed in Hanoi and at the Bai Chay tourism site in Ha Long.

The NewOpenWorld Organisation has sent a sample of the plaque to Vietnam for consideration. It said it hopes that Vietnam will invite representatives from six other countries which have wonders of nature to attend the ceremonies to share experiences in protecting and preserving wonders of nature.

The recognition ceremony will take place in Hanoi on Apr. 27 and in Ha Long City on May 1, with many interesting artistic performances.-VNA
