MAO Zedong proposed sending 10 million Chinese women to the United States, in talks with top envoy Henry Kissinger in 1973, according to documents released by the US State Department.

The Chinese dictator said he believed such emigration could kick-start bilateral trade but could also "harm" the US with a population explosion similar to China's, according to documents covering US-China ties between 1973 and 1976.

In a long conversation that stretched past midnight at Mao's residence on February 17, 1973, a cigar-smoking Mao referred to the dismal trade between the two countries, saying China was a "very poor country" and "what we have in excess is women".
