Architects use pavilion to paint contemporary image of nation with 'promising future' on international stage

For months, Su Dan has been traveling back and forth between Italy and China, tasked with the monumental job of overseeing the first national pavilion that China has built outside its borders.

The China Pavilion for Milan Expo 2015, which opened on May 1 and ends on Oct 31, is based on the design proposal by the 48-year-old Tsinghua University scholar and his team.
