As the Group of Eight summit in Ontario, Canada concluded Saturday, leaders from G20 nations have begun their fourth summit in Toronto.
In addition to those of the G20, leaders of the world's financial institutions and the United Nations are also attending the summit. UN Secretary-General Ban Ki-Moon arrived in Toronto Saturday.
Prime Minister Manmohan Singh of India and Prime Minister Jan Peter Balkenende of the Netherlands have also arrived to take part in the Group of 20 Summit. The official agenda of the Summit has shifted more towards economic and political affairs, and away from aid and development issues which have dominated past summits.
