Saudi Arabia will invest up to $25 billion in Pakistan over the next two to five years in different sectors, Pakistan's caretaker Prime Minister Anwaar-ul-Haq Kakar noted Monday, adding his government would also restore a stalled privatization process.

The South Asian nation is embarking on a tricky path to economic recovery under a caretaker government after a $3 billion loan program, approved by the International Monetary Fund (IMF) in July, averted a sovereign debt default.

Speaking to journalists at his official residence, Kakar said Saudi Arabia's investment would come in the mining, agriculture and information technology sectors and was part of a push to increase foreign direct investment in Pakistan.

There was no immediate response to a Reuters request to the Saudi Arabian government for comment on Kakar's remarks.

If confirmed, a series of investments worth $25 billion would be the biggest ever by the kingdom in Pakistan.

A longtime ally of Riyadh, Pakistan is dealing with a balance of payments crisis. It requires billions of dollars in foreign exchange to finance its trade deficit and repay its international debts in the current financial year.

Kakar did not specify projects Riyadh was looking at for investment, but last month, Barrick Gold Corp said it was open to bringing in Saudi Arabia's wealth fund as one of its partners in Pakistan's Reko Diq gold and copper mine.

Pakistan's untapped mineral deposits are conservatively valued at about $6 trillion, said Kakar, whose government is meant to be an interim set up to oversee national elections scheduled for November but are expected to be delayed by months.

Barrick considers the Reko Diq mine one of the world's largest underdeveloped copper-gold areas and it owns a 50% stake, with the remaining 50% owned by the governments of Pakistan and the province of Balochistan.

Kakar also said his government would push to complete two privatization deals, probably for state-run power sector entities, in the next six months and would also look to privatize another government-owned enterprise outside the energy sector.

Pakistan's state-owned enterprises have long been an area of concern, with bleeding financials adding to financial stress. Recently, Pakistan added struggling state-run Pakistan International Airlines (PIA) to the privatization list again.

The privatization process has largely stalled in the country, with the selling of state assets a politically sensitive issue that many elected governments have shied away from.
