Since its opening on May 1, the China Pavilion in Expo Milano 2015 has welcomed more than 2 million visitors, becoming one of the most popular pavilions in the expo.

From May 1 to Oct 31, about 145 countries, three international organizations and 13 nongovernmental organizations are scheduled to take part in the expo, which is expected to attract more than 20 million visitors.

Wang Rui, deputy pavilion director of China Pavilion Expo Milano 2015, told China Daily that this is the first time China has built its pavilion in a world expo independently.

This year, the country is presenting the second-largest foreign pavilion at the expo, which is themed "Feeding the Planet, Energy for Life".

The China Pavilion has a total construction surface area of 4,590 square meters, making it the second-largest pavilion after the Italian one.

In the past four months, the China Pavilion received an average of 10,000 daily visitors, and that could peak at 20,000, Wang said. But the pavilion's innovative design means visitors will not have to wait in long lines to get in, Wang said.
