i know that :
" Public procurement has a long history. Written on a red clay tablet,
found in Syria, the earliest procurement order dates from between 2400
and 2800 B.C. The order was for “50 jars of fragrant smooth oil for 600
small weight in grain”. Other evidence of historical
procurement includes the development of the silk trade between China
and a Greek colony in 800 B.C.
In the United States, government
procurement at the municipal level predates that of state and federal
governments."
what about the other countries? developed and in developing countries?
