Other highlights are three environmentally friendly bicycles from the Denmark Pavilion and an ancient Chinese vessel with three legs that weighs 469 kilograms and ranks as the world's heaviest jade tripod. The latter belongs to the Devnet Pavilion.

Organizers of the show said they plan to hold an online auction later featuring diamonds from Antwerp and chocolate souvenirs, also provided by the Belgium-EU Pavilion. Portugal is donating a soccer jersey signed by Real Madrid star Cristiano Ronaldo, while Spain will give jerseys and soccer boots signed by other members of the top-flight Spanish league team.

"At the moment, we're still finalizing negotiations with pavilions regarding their exhibits. Hopefully we'll be able to reach agreements on more items by early October," said Chen Zhen, who works at CBN's brand operation department.

Stine Guldmann, the director of the Denmark Pavilion, said that the bicycles it is donating are only the tip of the iceberg for what it is planning.

"The social bench that runs through our pavilion is made of steel, which can be reused after the Expo, while the furniture in our VIP facilities will be donated to the Nordic Center at (Shanghai's) Fudan University," she said.

Almost all of the pavilion's materials will be reused or donated to others, she added. The Danish Embassy in Beijing has purchased 35 of the pavilion's popular Copenhagen City bicycles for an online competition it will run soon.

Meanwhile, the Finland, Thailand and Belgium-EU pavilions have made donations to the Expo Museum. Finland will also give certain artifacts to a school in earthquake-ravaged Sichuan province. Finnish companies and governmental organizations in China built the school.

The UK Pavilion, also known as the "Seed Cathedral", is planning to donate the 60,000 seeds embedded in its structure's acrylic rods to primary schools in rural China. The Mexico Pavilion will send its hand-made kites and masks to Mexican firms operating on the mainland.

"We are also going to be giving away souvenirs like pins, cards, pictures and posters with each purchase to clear our stocks," said Alfonso Araujo, who manages the pavilion's merchandise outlet.
