Lithuanian President Dalia Grybauskaite addresses the ceremony.

Lithuania celebrates its National Pavilion Day today with a music concert at Oceania Square.

The Lithuania Pavilion within Zone C is themed "Blooming Cities."

The design of the Lithuania Pavilion is based on flowers in bud, symbolizing the vigorous, prosperous and booming country and its cities.

The pavilion shows the achievements in sports and scientific development that Lithuanians have made, and a 360-degree screen allows visitors to feel like they are flying above the country.
