Sartaj Aziz said here that the SCO took a unanimous formal decision to admit Pakistan (and India) into the grouping dominated by Russia and China.
"10th of July, 2015 was a very important day in the diplomatic history of Pakistan," he said referring to the endorsement by the SCO summit at Ufa, Russia to accord membership to the two South Asian neighbours.
"The process has been launched and after formalities are completed like ratification of SCO documents, Pakistan will become a full-fledged member of the SCO," said Aziz.
Aziz said that another major development of "historic proportions" was the meeting of Prime Minister Nawaz Sharif with Russian President Vladimir Putin on the sidelines of SCO.
