Chinese President Hu Jintao cut short his stay in Italy after concluding a state visit to the country and left for home on July 8 local time due to the situation in northwest China's Xinjiang Uygur Autonomous Region. State Councilor Dai Bingguo will attend the summit of the Group of Eight and major developing countries to be held in the central Italian city of L'Aquila on Hu's behalf. The date for Hu's state visit to Portugal will be fixed by the Chinese and Portuguese sides some time later.
