The two-day China-US Business Forum has ended with meaningful exchanges and communications between the largest developing country -China and the most developed country- the United States.

The theme of the forum is "expanding exchanges and cooperation for a mutual-benefit and win-win tomorrow".

About 180 experts, government officials and entrepreneurs have had a series of brainstorms on Sino-US economy and trade. Participants have recalled the Sino-US trade development process and the current situation in market access, trade balance and RMB exchange rate.

Sino-US trade started in 1979 when the two countries signed the agreement on trade relations. Bilateral trade volume then was $2.45 billion, but rocketed to $211.6 billion in 2005, 80 times more than that in 1979.

Today, the US has become China's second largest trade partner while China becomes the US third largest and fastest growing export market.
