In theory, state councillors are to assist the Premier and Vice-Premiers to oversee various government portfolios. They can also represent the State Council (and in turn, Government of China) on foreign visits. State councillors are part of a Standing Committee of the State Council, alongside the Premier, Vice-Premiers, and the Secretary General of the State Council. The organ holds weekly meetings. In practice, a state councillor's portfolios can be very wide-ranging. State councillors often accompany China's higher dignitaries on trips abroad - as was the case with State Councillor Tang Jiaxuan from 2003–08, and Dai Bingguo from 2008–present. Dai also became China's representative at the 2009 G8 summit in Italy when President Hu Jintao decided to cut short his attendance to return to China in order to deal with the July 2009 Ürümqi riots.
