Many Italian visitors, including high-level officials, have expressed their fondness for the pavilion. Margherita Barberis, director-general of Foundation Italy China, told China Daily that she went to the pavilion a few times already, but it still impresses her every time she visits.

"I come to the expo once or twice a week," she said. "The China Pavilion is very impressive and beautiful, and the organization of it is well done. It is a rare case among the popular expo pavilions in that it does not require long waiting times.

"I think the most impressive thing in the Chinese pavilion is the wheat field made up of more than 20,000 of LED lights," she said. "China is one of the countries in the world with the best solar energy industries, and that is reflected by those LED lights in the venue."

The exterior of the pavilion is also very beautiful, Barberis said. She said because she has been visiting China frequently for 15 years, she had thought that there would be nothing that would surprise her. However, when she saw the pavilion, it brought a warm feeling, like going back to China.

Dominici Anna, an Italian white-collar worker, had to attend a meeting near the expo, so during her one-hour break, she chose to visit the Chinese pavilion for a taste of the expo.

"The peaceful display of the pavilion is good, other pavilions want to show a lot of high-tech effects, but I like the beauty of nature presented in the China Pavilion," she said. She also mentioned that although the pavilion is popular, she still can get in without waiting too long.

Fabrizio Grillo, secretary-general of the Italy Pavilion, told China Daily that it was "so nice and impressive to see so many differences among all China's different regions, provinces, the historical traditions".

This year is also the first time for a China Pavilion at an expo to combine the functions of showcasing the country and promoting economic trade, Wang said.

"Between Italy and China, there are many sectors that offer the possibility of build bilateral economic relations," Grillo said.

Since 1982, the China Council for the Promotion of International Trade has organized the China Pavilion for 15 world expos.

According to Wang, the development of China pavilions in the previous expos is a process of gradual improvement. Compared to previous years, Chinese authorities have placed greater emphasis on the economic and trade aspects. This change results from the communication with other countries, "at the expo platform we not only showcase ourselves, but also learn and absorb others' advantages", Wang said.

"We learned from other experienced countries such as Italy, France, Germany and the United Kingdom. Those countries are very dedicated to the expo and to the promotion of their economic development and trade relationship through the expo. From the design and exhibitions of their pavilions, you can feel the enthusiasm of promoting trade ties," Wang said.

"Slightly, step by step, we adjust our design and concept of the pavilion to adapt to new international trends," he said.

China's provincial governments have also organized a series of higher-end economic and trade promotional activities for investors and projects through the platform.
