China is ready to make joint efforts with the United States to further promote bilateral constructive cooperation so as to benefit the peoples of the two countries and the world, said Chinese Foreign Ministry spokeswoman Zhang Qiyue Thursday.

Zhang made the remark when asked to comment on the future Sino-US relations after George W. Bush was reelected the US president on Wednesday.
