In his speech, Prof. Andrew Chi-Chih Yao expressed his gratitude to scholars from University of Aarhus (Denmark), Chinese University of Hong Kong and University of Sydney for their attendance. He said that this conference was quite successful and it is sure that the communication and cooperation between Danish and Chinese researchers will be strengthened.

CTACC 2009 concluded successfully after the panel discussion on the sixth day of the conference, during which scholars from Denmark not only carried out academic exchange with professors of ITCS, but also have a taste of Chinese culture. It is beyond doubt that this conference will bridge the distance between Chinese and Danish scholars, and most of them wish to have a further chance to visit ITCS of Tsinghua university.
