Sources in the government said that Prime Minister Shahid Khaqan Abbasi after consultations approved the appointment and Siddiqui is expected to take up responsibilities next month after completion of formalities.
His appointment comes at a time of fresh strain in ties between Islamabad and Washington after the US successfully moved the Financial Action Task Force (FATF) to place Pakistan on the global terror financing watch-list.
Siddiqui was appointed as the special assistant to the PM on economic and business matters in August last.
Siddiqui has no direct experience of diplomacy as he served at different positions in various business and commercial entities in Pakistan and abroad. He was honoured by the World Economic Forum as a Young Global Leader in 2014.
