US President Barack Obama is to address the two-day meeting, to which China has sent Vice Premier Wang Qiahan and State Council Dai Bingguo.
While, US Secretary of state Hillary Clinton and treasury secretary Timothy Geithner made a joint appeal to Beijing to work together to spur global growth.
"Simply put, few global problems can be solved by the US or China alone. And few can be solved without the US and China together," Geithner and Clinton wrote in an article published on Monday, Jul 27 in The Wall Street Journal.
"The success of the world's major economies in blunting the force of the global recession and setting the stage for recovery is due in substantial measure to the bold steps our two nations have taken," they said.
Charles Freeman, a China expert at the Center for Strategic and International Studies, a Washington think-tank, said the dialogue's main purpose was to build confidence between Washington and Beijing.
